A man walks into synogogue 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 religious 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 around its neck.
"Morris," says the man to the dog, "daven (pray) !".
"Woof!" says the dog, stands on his hind legs, opens the tallis bag, takes out a kippa and puts it on his head.
"Woof!" says the dog, stands on his hind legs, opens the tallis bag, takes out a siddur and starts to daven in perfect Hebrew.
"That's fantastic," says the shammas, "absolutely amazing, incredible! You should take him to Hollywood, get him on television, or get him into a Yeshiva and your dog Morris could become a Rabbi !!"
"You speak to him," says the man, "he wants to be a lawyer."
