Anthony and his wife, Maria, are planning to visit his grandmother, so he calls her for directions to her new apartment. She tells him how to drive there, and adds,
"You comma ina the fronta door of the apartmenta building, anda I'ma in apartmenta 306. There isa bigga panel with alla the apartmenta numbers, anda you pressa 306 witha you elbow. I will buzza you in, and the elevator is ona the right side. Whena you get an elevator, you pusha the number '3' witha your elbow, and turna left whena you leave the elevator. I'ma in 306 anda you knock ona the door witha you elbow."
The grandson is confused, and asks, "I understand all that, Grandmama, but why do I have to use my elbow everytime?"
The grandmother shouts, "WHAAAT?! You coming empty-handed???"
