Boiled Water

Listen up, lil' buddy. This joke is for smart people like me. "RIP" means "Rest In Peace." Get it? We use it when someone dies. The joke is funny because boiled water turns into mist. So, instead of saying the water is dead, we say it "will be mist" because it's turning into mist, which sounds like "missed." You are probably someone that wears a helmet at home. SAD!
