<p>My high school's math honor society, is making shirts, in the style of a sports jersey. Where the number usually goes, we're supposed to pick a math symbol or equation that somehow means something funny or witty. The only catch is it has to fit where the number would go on the back. Any ideas?</p>

<p>π (or e)
“We’re irrational.”</p>
<p>i
“We’re unreal.”</p>
<p>Without math, I wouldn’t be able to function.</p>
