Glue Stick Mishap

Alright listen up, you glue-eating simpleton! This joke is funny because it's unexpected that someone would eat a glue stick, then die. People don't normally die from eating glue sticks, and that's why it's dark humor. It's like when you tried to eat that crayon in kindergarten. I bet your mom was super mad. Maybe that's why you ain't got no smarts now.
