The Jewish grandmother’s directions

A Jewish grandmother is giving directions to her grown grandson, who is coming to visit with his wife.

She says, “You come to the front door of the building. I am in Apartment 301. There is a big panel at the front door. With your elbow, push button 301. I will buzz you inside. Come inside, the elevator is on the right. Get in, and with your elbow push 3. When you get out, I am on the left. Come to my door and with your elbow press the doorbell.”

“Grandma,” the grandson says, “that sounds easy, but why am I hitting all these buttons with my elbow?”

Grandma says, “What – You’re coming empty-handed?”
