Surgery

"Henry, you're never gonna believe this."

"What?"

"Last week we had to surgically remove a guy's head from his own ass."

"No way!"

"It was quite difficult. It was so far up there, he actually looked like a normal person. We had to do a complete reversal, you know."

"Holy shit."

"Yes, and the craziest thing is there are more people like him out there. They're just really difficult to spot, because as I said, they look completely normal!"

"That's terrifying."

"It's a terrifying world indeed, Henry."
