Duck Food ?
 

A duck waddles into a hardware store and quacks "ya got any duck food?"

The store manager says "no, this is a hardware store, no duck food".

So the duck waddles out.


The next day the duck waddles in and asks "Ya got any duck food?"

The manager looks a little pissed and says "No, no duck food. We sell hammers and nails and lightbulbs and so on, not duck food!" and the duck rushes out.


The next day the duck waddles in again.."Hey pal, got any duck food?"

The manager screams "No, no duck food here!"

The duck quacks "can you check the back?"

"No, I don't have to, and if you ever come in here again I'm going to take this hammer and these nails and nail your bill to this floor!"


The next day the duck waddles in .. "Hey buddy, got any nails?"

The manager, relieved at a sane request, says "Actually, no, I sold all our nails to a lumber company this morning"

The duck looks up with bright eyes and says "Great! got any duck food?"
