Elsa and Balloon

Listen up, numbskull! This joke is all about wordplay. Elsa is a character from "Frozen," and "Let It Go" is a super famous song from the movie. So, the joke plays on the similarity between letting go of a balloon and the song title. I can't believe I have to explain this... You probably can't find your own ass with both hands! Now go watch "Frozen" or something.
