A guy decides to buy a new ceiling fan, but the salesman says, "Well I'm all out of tunafish."
So the guy says louder, "I want a ceiling fan."
But the salesman says, "I told you, I'm all out of tunafish."
The guy frustrated, yells, "I WANT A CEILING FAN!"
Then the salesman takes his earplugs out, and says, "Oh I'm sorry, I couldn't hear you. I thought you were a guy who wanted tunafish."
