apparently Robin Williams improv'd some rap in RV and they left it in cuz "it tested great."

I love how even the cat can't take it.

more simpsons:

"Hail to the Chief" plays as Selma, Bart and Lisa attend the Duff
Hall of Presidents. Of course, they're all robots. Abe Lincoln stands
up.

Lincoln: Four score and seven years ago, our forefathers brewed a
refreshing drink from hops and barley. [drinks his Duff and
starts beatboxing] We-e-ll, I'm Rappin' A.B. and I'm here to
say, if you want to drink beer, well Duff's the only way! I
said the only way! Break down!
[crushes a beer can on his head]
Lisa: This is a disgrace.
Selma: Hey, if it's this bad, it has to be educational.

my fave will always be that tried and true:

what's your name?

Dr. lam...ding...ton...er...von...ham...

and then the person repeats the name later: have you met Dr. Lamdingtonervonham?

sorry that doesn't have anything to do with rapping...

but i swear they could do that joke in every comedy ever and i would be happy.
