Hey, dummy! The joke is a play on words. "Fresh Prints" sounds like "Fresh Prince," which is a reference to Will Smith's old TV show, "The Fresh Prince of Bel-Air." It's funny because you wouldn't expect to find Will Smith by looking for literal fresh prints in the snow. You probably watch that garbage reality TV, don't you?
