The Rabbi asked, "What are doing here with a dog?"
Bernie replied, "The dog came here to pray."
"Oh, come on." says the Rabbi. "I don't believe you. You are just fooling around; that's not a proper thing to do in temple."
"Honest," says Bernie, "Its true!"
"Ok", says the Rabbi (thinking he would call Bernie's bluff), "then show me what the dog can do."
"OK" says Bernie nodding to the dog...The dog proceeds to open up the barrel under his neck and removes a yarmulke, a tallis (puts them on his head) and prayer book and actually starts saying prayers in Hebrew! The Rabbi is so shocked he listens for a full 15 minutes.
When the Rabbi regains his composure, he is so impressed with the quality of the praying he says to Bernie. "Do you think your dog would consider going to Rabbinical school????"
Bernie, throwing up his hands in disgust says, "YOU TALK TO HIM! He wants to be a doctor!"
