You: You are such a flick pain.
Me: You are flick pain to my sight.
You: You are such a flick pain.
Me: You are flick pain to my sight.
Listen up, buttercup. This joke is all about turning the insult back on the insulter!

If you understood it the first time then you'd be out there makin' millions instead of listening to me.
