fuck it...let's make lists... favorite humorous rap lyric

[Certain]

From a punchline perspective, it's probably MC Rise: "I found out just recently that other people rhyme too."

From a storytelling perspective, J-Live's "she used to be a dude."

But laugh-out-loud funny has to be Kurupt on Xxplosive:

West coast shit nigga
Overdosage - imperial pistols ferocious
Fuck a bitch; don't tease bitch, strip tease bitch
Eat a bowl of these bitch, gobble the dick
Hoes forgot to eat a dick can shut the fuck up!
Gobble and swallow a nut up, shut up and get my cash
Backhanded, pimpslapped backwards and left stranded
Just pop ya collar, pimp convention hoes for a dollar
Six-Deuce in a plush, six-deuce impala
Pimpin hoes from Texas to Guatemala
Bitch niggaz paid for hoes, just to lay wit hoes
Relax one night, and paid to stay wit hoes
Captain Save'Em all day (bitch) well save this dick
Bitch nigga, you more of a bitch than a bitch
You ain't into hittin pussy, or hittin the switch
You into hittin bitches off of the grip, you punk bitch
