A man walks into shul with a dog. The shammas comes up to him and says, "Pardon me, this is a House of Worship, you can't bring your dog in here."

"What do you mean," says the man, "this is a Jewish dog. Look."

And the shammas looks carefully and sees that in the same way that a St. Bernard carries a brandy barrel round its neck this dog has a tallis bag round its neck.

"Rover," says the man, "daven!".

"Woof!" says the dog, stands on his hind legs, opens the tallis bag, takes out a kipa and puts it on his head.

"Woof!" says the dog, stands on his hind legs, opens the tallis bag, takes out a tallis and puts it round his neck.

"Woof!" says the dog, stands on his hind legs, opens the tallis bag, takes out a siddur and starts to daven.

"That's fantastic," says the shammas, "absolutely amazing, incredible! You should take him to Hollywood, get him on television, get him in the movies, he could make a million dollars!!"

"You speak to him," says the man, "he wants to be a dentist."
