A Jewish man walks into his synagogue on Yom Kippur with with his dog. The Rabbi stops him at the door and says “Moishe, what’s the matter with you? You can’t bring a dog in here.”

“Don’t worry, Rabbi,” replies Moishe, “Isaac here is just as orthodox as I am, and he’s come to pray.” And as soon as he says that, the dog stands up on his hind legs, pulls a yarmulka out of Moishe’s pocket, grabs a prayer book and starts praying in perfect Hebrew.

The Rabbi is amazed. “Wow,” he says, “this is incredible, Moishe. You should make this dog become a Rabbi!”

“You tell him that, Rabbi,” replies Moishe. “He wants to be a doctor.”
