Accent lighting Puns

My dad has a slight arabic accent. We approached an orange light and he said:

Dad: Another orange light

Me: It's because you're bad luck

Dad: No, I'm with numbers

Me: What?

Dad: I'm a lock with numbers, not a padlock

A man in Switzerland is trying to get his grandfather clock fixed, and brings it into a clock shop.

The clock shop attendant asks the man "What seems to be the trouble?"

"Well, the clock tells time just fine. However, as you can hear, it ticks... But doesn't tock."

"Hmm, I think our Horologist will need to take a look at your clock. Please bring it into the back."

So the man wheels his clock into the back room, and there is an old, balding man, wearing a lab coat and thick horn rimmed glasses. He asks the man in a thick German accent "What seems to be the problem?"

"Well, you see, this clock ticks, but it doesn't tock."

"I see," says the horologist. He turns on a single light bulb, and turns off the lights to the room, and pulls out some pliers from his labcoat, and says, in his thick German accent...

"We have ways of making you tock."

Dad: How many Germans does it take to screw in a light bulb?

Me: ehm?

Dad: 'Puts on German accent' One.. we are efficient and have no sense of humour

Then he starts laughing vigorously and walks away proud as a peacock
