Me and Robert got bored on the 3 1/2 hour plane trip last month to Sacramento, so we played this game where I write a line, then he writes one that rhymes, then he writes the next and I make one that rhymes etc. They always turn nasty (my lines are blue, his are in red):

It was a dark and stormy night
And I was looking for a fight
This tosser looked my way
So I told him "You are gay!"
He kicked me in the ear
So I pissed in his beer
And shoved my pool cue up his ass
When I pulled it out he passed some gas
His fart made my glasses foggy
I bent him over and we did it doggy
He downed his beer and said "Thanks, buddy."
Then I saw my dick was bloody.
He said "That's not blood, that's JAM that is."
I said "You fucker, are you taking the piss?!
Feeding jam doughnuts to your hamster?!"
He said "I get off any way I can sir."
