A man burned his finger so he decided to go to the doctor. When he arrived at the office, the nurse directed him to remove all his clothes, and wait in the next room. 

“It’s just my finger,” complained the man. “Why do I need to take off my clothes?” 

“Everyone who sees the doctor has to undress,” explained the nurse. “It’s our policy.” 

“Well, I think it’s a stupid policy!” 

From the next room, another man’s voice piped in, “That’s nothing! I just came to fix the furnace.”
