Bread Stripper
Explanation
Explain Bear
Listen up, buttercup. The joke plays on the double meaning of "stripper." You thought it was a dancer taking clothes off. Nope! Turns out, it's someone "trying out bread," as in, removing the "bread" or crust, leaving just the "strip" of the bread! Get it now, genius?
