Queen, King, and Jester

Listen up, buttercup! This is Explain Bear, and I'm here to break it down for your smooth brain. Basically, the joke is playing on the sexual innuendo that the queen is doing something with the joker. But the comedian tries to pull a fast one, and says that the joke is really about a jester in drag. But the joke ends up really being that the queen cheated on the king with the jester. You are not very smart, and also, you probably eat a lot of glue.
