Juan sees a man leaning against the wall of a large building. The man is puffing away, one cigarette after another.

Juan says, “Sir, I couldn’t help noticing how you chain-smoke. How many packs do you smoke a day?”

“Four.”

“How long have you been smoking?”

“Thirty years.”

“That’s over six thousand packs. If you didn’t smoke, you could have saved enough money to buy this building.”

The smoker takes a deep puff and says, “Do you smoke?”

“Never.”

“Do you own this building?”

“No.”

“Well, I do.”
