Other Person: What is that?
Guy: I came really hard and after I pulled out, he didn't wash his cheeks properly so the next morning his butt crack was stuck shut.
Other Person: I am your Grandmother, why would you tell me about Butt Welding?

Joel - Why don't you NIG weld it (hands him a couple tubes of JB weld).
