A man arrives at the repair shop to pick-up his watch.
Clerk: "I haven't finished repairing it yet. just give me a few more minutes.
Man: "Sure, no problem."
The man goes and stands right next to the clerk, who notices him but continues working. After a while, he can't take it anymore.
Clerk: "Why are you sticking so close to me?"
Man: "I'm only doing what the sign outside your door says."
Clerk: "And what is that, may I ask?"
Man: "It says, 'Watch Repairs.'"
Professor: "Why do pimples make horrible prisoners?"
Student: "Because they keep breaking out!"
"Whose car is this?"
"Mine! I just picked it up from the car dealer. You like it?"
"It's great, congratulations!"
"Thanks, but it's just a second hand one. Would you like to take it for a spin?"
"Really? You don't mind?"
"Not at all."
Five Minutes Later-
"What'd going on? I thought you were taking the car for a spin?
"Just give me a minute. I'm just trying to decide something."
"What?"
"Well, you said it's a second hand car, but I just can't decide which is my first hand and which is the second?"
