Up For Adoption

Alright, listen up, buttercup. This joke is all about wordplay. The dude is saying Rob owes him money but then hits him with a "sucky sucky my thang" which sounds like he's calling Rob a bad lover. But really, it's a setup to reveal Rob is "up for adoption" because he ain't paying his bills. People who don't pay bills usually eat crayons like you, goofball.
