Substitute teachers’ aide or paraprofessional (or whatever it’s called where you live). My brother does this. He could work full time if he wanted, but he gets to decide which jobs he accepts and he chooses to not work full time. No certification needed.
In most places, there are minimum requirements for even paraprofessional substitutes. At the very least, you will need to get fingerprinted, and have background checks done.
I’ve worked in public education my entire career…I wouldn’t say it’s “fun”. Many of those para jobs are with very need students. If you are up for it…go for it…but it’s not my idea of “fun”.
The most fun I ever had at a job was bartending in college! Everyone was happy!
Yes, looking at @conmama thread title - “Fun Part Time Jobs. Anyone have one?” Substitute teaching COULD be fun but largely it’s hard work that might not always be a lot of “fun”. Enjoyable, maybe. Rewarding, probably. "FUN? Not sure!!! 
She also may be asking what “fun” part time jobs do any of us have.
To me working in a book store would be “fun”.
Other fun jobs I can think of:
Helping with estate sales.
Conference assistant
Working in a coffee shop
Assisting with cooking classes
Working someplace that bleeds happy. And that would NOT be Disney World for me!!
There are fun jobs and there are jobs that people can actually get with the other requirements the OP has specified. I agree that being a paraprofessional isn’t necessarily fun. But it checks several of the other boxes.
One of my part-time jobs is fun (proofreading for a publisher of children’s books) but I often have to do the work on weekends (something the OP wants to avoid) and the publisher has only one location (in my community), so it’s not generally available work.
@thumper1 I lived in a state where you qualified to be a substitute HS teacher as long as you had passed a single college class. Wee!
As a parent, would you be comfortable with that ^^^ being the only qualification necessary?! Yikes!
The definition of fun can be in conflict with the definition of job. 
For me, the ability to be busy when I want to be busy, earn some money while I am busy, and say no to work when I don’t feel like working is “fun” as far as work goes.
Uber driver for me. I will only take people to and from airports and I prefer long trips.
How about someone who waits in line for other people? Folks hire people to stand in line for them, like at the new restaurant in town. Check out a website called “task rabbit.” All sorts of jobs are advertised or wanted.

Dang! I work part time as a RN in a plastic surgery OR (not the office), and I get diddly! Well, I get paid, but no freebies. :((
So, I’m going ahead and filling out the application for substitute teaching. I’m going to investigate other opportunities also. The application is asking about my prior employment. As I’ve said, I was part of a 15 percent company wide lay-off, and being one of the only part-timers it made sense. I was ther 28 years.
They ask several questions that I feel hurt my chances of even being asked to talk to. Can they contact my employer, was I ever asked to leave for any reason (I have a paragraph to explain).
Should I just say no and move on? Except one of my references is my former supervisor. Ugh…what to do? If I tell them they can’t contact my former employer that raises a red flag. But is the company allowed to say why I’m not there? Or just the dates I was employed.
I’d rather not bring this up. Actually, for my contract work I did, I did bring answer the question as to why I left. It I was in an interview, they could see me, hear me…and believe me. I was hired later that day.
So, it’s not that I won’t ever tell, it’s just on an online application, I think it’s a black mark. What to do?
Getting downsized is NOT going to hurt your chances of being hired as a substitute teacher. Answer honestly…it’s the right thing to do.
They are allowed to say anything that is true. However, many companies have a policy that they will only give dates of employment, maybe are able to answer the question “is this person eligible for re-hire?” with a yes or no answer.
There is a huge need among small businesses for someone with accounting and Quickbooks knowledge. It’s intuitive and user-friendly, especially for someone with a base in accounting. I think you could make a very flexible gig with this (and I know their companies and their CPAs would be thrilled Maybe consider taking a Quickbooks class somewhere and see if you are interested?
The part time job I enjoyed the most was working at the Munger Africana library at Caltech. He had an enormous collection which was available for the students. My only previous experience had been shelving library books at Harvard and living in Africa. I had to catalog books, file newspaper clippings, put back books and help students find materials for their papers.
The most exhausting job I’ve had was teaching watercolor classes after school to elementary age kids. I’d consider doing an adult class. I could never do substitute teaching, but my Mom loved it, though I think she liked teaching her own class better.
If you want to try retail, might want to look at small, local businesses. Several I know here (gift/decor, children’s clothing, etc) have shorter hours ( close at 6) and are not open on Sundays. Often not open on holidays that chains are. And any bookkeeping skills might make you doubly valuable.
Quickbooks is pretty easy and intuitive to learn. I use it to keep the books for the small company H and I have outside of our regular jobs. There are probably classes you can take at a local cc or even online.
You can put down you left your company due to down sizing. It is very common and doesn’t have negative connotation.
I used to fantasize about being a roving payroll person. I’d have three or four small businesses that I’d go to once every two weeks. I would swoop in and prepare the payroll, freeing up whoever was tasked with that responsibility and then move on to the next company. I got this idea when I worked at a company that used a payroll service and the guy who owned the payroll service told me about how much time he had to spend training the payroll person at his client companies. I thought there might be an opportunity there. I never followed up although I do payroll now at my current job (but without a payroll service.)
