The bartender sees him and calls out, “Get out of here with that dog!”
The man walks up to the bar and says to the bartender, “But this isn’t just any dog … this dog can play the piano!”
“Pull the other one”, the bartender replies. “Well, if he can play that piano, you both can stay and have a drink on the house”.
So, the man sits the dog on the piano stool, and the dog starts playing the piano.
He plays some Ragtime, some Mozart and the bartender and patrons are amazed and thoroughly enjoying the music.
Suddenly, a bigger dog runs in, grabs the small dog by the scruff of the neck, and drags him outside.
The audience and bartender are in shock at what just happened.
The bartender asks the the man, “What was that all about?”
The man replies, “Oh, that was his mother. She wanted him to be a dentist”.
