Third Grade Stand up Comedy

Two jokes from dinner tonight
Blond twin: "What does a mouse need?"
Dad: "What?"
Blond twin: "Mouscles. Get it not muscles, mouscles."
Blond twin: "What do you call a sleeping bull?"
Brunette twin: "Bulldozer. Get it? Bulldozer."
Mom and Dad laugh because the girls are laughing so much. It's like these are the funniest jokes they've ever heard. Sometimes dinner is fun.
