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."
