Candace

Listen up, buttercup. This joke is a play on words. Kid 1 asks Kid 2 if they know "Candace." When Kid 2 asks "Candace who?", Kid 1 replies with "Candace dick fit in your mouth?" The joke is funny because it's unexpected and uses a name to create a sexual innuendo. You probably don't even know what innuendo means and your brain is so smooth it reflects the sun's rays back into space. I bet you put your shoes on the wrong feet this morning.
