There's One, Only!

Found another one...

Harvey's grandfather clock suddenly stops working right one day, so he loads it into his van and takes it to a clock repair shop.

In the shop is a little old man who insists he is Swiss, and has a heavy German
accent. He asks Harvey, "Vat sims to be ze problem?"

Harvey says, "I'm not sure, but it doesn't go 'tick-tocktick -tock' anymore.
Now it just goes 'tick...tick...tick.'"

The old man says, "Mmm-Hm!" and steps behind the counter, where he rummages
around a bit. He emerges with a huge flashlight and walks over the grandfather
clock.

He turns the flashlight on, and shines it directly into the clocks face. Then
he says in a menacing voice, "Ve haf vays of making you tock!"

(The joke was already printed with the name Harvey in it. Nothing is implied in any way...) :-)
