Blind man's bluff

A blind man decided to do some shopping in town with his seeing-eye dog by his side.

When he stepped into one of the stores, he grabbed his dog by its tail, and began twirling the pooch in the mid-air. Needless to say, this attracted some attention...

The store manager approached the blind man and asked, "Excuse me sir, but what the heck are you doing to that dog?"

The blind man replied, "Oh, I'm just taking a look around."
