A duck walks into a convenience store

He says to the clerk “do you have any grapes?” The clerk replies, “no sorry, we don’t

have grapes.” The duck walks out and returns the next day. “Do you have any grapes?”

The clerk replies “no we still have no grapes.” The duck leaves but comes back the

next day “do you have any grapes?” The clerk says “listen you stupid duck. If you

come back here tomorrow and ask if I have grapes, I’m going to nail your feet to the

floor.” The duck waddles out but sure enough returns the next day. “Do you have any

nails?” he asks the clerk. The clerk says “no we don’t have any nails.” The duck says “in

that case do you have any grapes?”
