What's the funniest song you ever heard?

“The Legend of the USS Titanic” as performed by Jaime Brockett and Chris Smithers

A sampling:

You wanna 'nother toke, Captain?...... And the Captain, he say....... RIGHT!!!!!!!!..............

.......He says “I am commencing to hold it in!”

He walked around the wheelhouse.
He went downstairs
He laid down.
He get up, he ran in the other room.
He sent a radiogram.
He came on back in.
He took a shower.
He come out.
He shaved.
He laid down.
He got up again.
He turned on the television.
He turned off the radio.
He played a game of cribbage.
He read his masked marvel comic book.
He walked thru the kitchen,
made a cup of tea,
made a cup of coffee,
sat down,
ate a piece of pie,
went upstairs,
played another game of cribbage,
went back in,
finished his other masked marvel comic book,
laid down,
he had the television, the radio, the egg beater, the air conditioner n’everything's all goin' at once. He walks up on deck and this is fifty two minutes later n' this cat ain't breathed yet!
So the First Mate see him standin' up there on the rail he's all puffed up like a balloon!
And he say, “ya gotta let it out, Captain!

There are actually many, by many artists. No list would be complete, however, without mention of Wierd Al. Songs like "Eat It" and "Like a Surgeon" are hilarious.
