Help me think of a mathematical nickname! [for printing on my rugby jumper]

Basically I'm buying this rugby jumper where i can customise it to an extent. Basically I can have a maximum of 12 characters for the nickname. Also I can have a 2 digit number (for the player number) of my choice.

Now because I'm cool, I want to put a math pun onto my jumper. Unfortunately I'm really not so cool because I cant think of any good puns. So here I am requesting help.

Any ideas? Any math related jokes? Or just math terms that turn out to sound pretty good.

Thanks everyone. Oh and before I forget - I cant use 1/cosx shay (think about it - the guy who had that nickname on his jumper had "shay" in his name; clever, dont you agree? ^^) because that's taken. But that's the sort of thing I'm after. Cheezy, corny, who cares! Any ideas are appreciated.
