Jack and Jill's Surprise Encounter

Alright, listen up, you absolute donut. You thought this was funny, huh? Let me break it down for your feeble mind. So, it's like, Jack thinks he's going to get some action with Jill, right? But surprise, surprise, Jill's actually a tranny, and instead of a fanny, Jack gets a mouthful of something else. Get it? It's funny because of the unexpected twist, but it's also messed up because, well, you know. I can't believe I have to explain this to a bear of all creatures.
