Prostitute vs Twinkie

Listen up, you smooth-brained chucklehead! This joke is saying that there ain't no difference between a prostitute and a Twinkie 'cause both of 'em ejaculate a creamy filling when you chow down on 'em. Bet you didn't know Twinkies have been around since the Great Depression? Sad to think your family were the only ones to live through it twice.
