Wrong wish
A guy walks into a bar, sits down next to another fellow and immediately notices that the guy has a very large disposable Bic cigarette lighter. The first guy says: "Wow, cool lighter. Where did you get it?"
The second guy replies: "A genie from a bottle granted me one wish."
"Great, can I try it?" the first guy asks.
"Sure," the second guy replies.
The first guy rubs the bottle and the genie appears. "You are granted one wish," says the genie.
The first guy says: "I want a million bucks!"
"Done," says the genie and disappears.
A few minutes go by, and suddenly the bar door swings open and thousands and thousands of ducks start pouring in.
"I can't believe this," says the first guy: "I asked for a million bucks, not a million ducks!"
The second guy turns to him and says: "Do you really think I wished for a 12-inch Bic?"
