The sound of somebody jerking off listening to clown porn and whistles in the background

Uh, my dog. Um, children. The children that I have in my basement. Um, good answer. I don't know what else to say. Oh wait, wait, wait, wait, wait. I gotta sneeze. Shit. That was completely unnecessary, but yeah.
