Uncle Ralph

He is a typical weird, fat, smelly, jobless, homeless guy with a super long beard. He normally visits your house with food stains all over his shirt. He also is definitely on drugs. Stay away from your Uncle Ralph unless you want to be kid-napped and fed to some bears in the forest.

Mom: "Your Uncle Ralph is coming over today."
Kids: "NOOOOOOOOOOOOO!!!!"
