I always like a good pun so: The Primes New Roman, I like it on so many levels. Also the team named Salt and Vignere elicited a snigger, as did Universally Challenged. The Mathemagicians seems popular in various forms, for good reasons. And I no one ever expects The Spanish Inquisition (to win, but who knows).
