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.”
