Speech and debate team sweatshirts?

my schools speech and debate team is getting sweatshirt and so far none of the designs weve come up with have fit the bill (either have been unusable or jus weird) so i was wondering if you guys have any ideas. no copywrited things, obviously. btw our mascot is a panda :) and we would prefer something witty. for example some of our previous ideas were dont hate... DEBATE (principal wont like it), the REAL N.F.L.[National Forensics League] (too commonly used), and We Kick Aff [aff is short for affirmative cases] (principal wont like it). so yes, help would be appreciated, thanx ;)
