We won't need to attach the actual XKCD comic soon. It'll be like...

DUDE 1: 129.
GANG: Hahaha!
DUDE 2: 32!
GANG: Heh heh heh, good one!
DUDE 3: Hey! What's going on?
DUDE 1: We gave every joke a number so we don't have to actually tell it.
DUDE 3: Ah...
DUDE 2: 320.
Gang: *rolls on floor laughing*
DUDE 3: That must've been a good one.
DUDE 1: Yeah! No one's heard that one before.
