"I'm Comic Sans, Asshole," from McSweeney's Internet Tendency. (This was sent to us separately by Shirin Dubbin, CKHB, Derek Gentry, Barbara Ann Wright, and like three other people--sorry if we forgot you! WHAT A DELIGHT IT IS TO BE KNOWN SO WELL BY OUR BELOVED AUTHOR-FRIENDS!)

Also, eagle-eyed Author-friend James alerted us that Tom Gabor, originator of beloved-by-Author-friends font joke "I shot the serif," is selling prints of this item here.
