This is the one sketch that sticks in my mind the most:
The guy is talking about banks, and how they punished him for not having enough money.
He didn't have any money going into his account so they charged him,
After a while he still had no money going into his account so they charged him again, this took him below zero
So now he has less than no money, if someone offers him something for free he can't afford it, it's beyond his means
Then he goes on to lament that if you have lots of money, banks will give you more
I promise it was a lot funnier than I've paraphrased here

Thanks in advance!
