A biker goes to a store looking for a muffler.
The store owner said he doesn’t sell mufflers.
The next day the biker was back looking for a muffler.
The store owner said he doesn’t sell mufflers.
The following day, the biker was back again asking about a muffler and the store owner recognized him and got irritated.
“Next time you come back looking for mufflers, I’m going to nail you to the wall!”
The day after, the biker was back but this time asked,”Do you have nails?”
“No,” was the reply.
“Ok, do you have a muffler?”
