A Jewish grandmother giving directions to her grown grandson who is coming to visit with his wife.
"You come to the fromt door of the Golders Green block of flats. I am in flat mumber 32.
There is a big panel at the front door. With your elbow, push button 32. I will buzz you in.
Come inside, the elevator is on the right. Get in, and with your elbow hit 14.
When you get out, I am on the left. With your elbow, hit my doorbell."
"Grandma, that sounds easy, but why am I hitting all these buttons with my elbow?"
"You're coming empty handed?"
