70 year old Morris has cancer and is in bed, close to dying. His wife Hetty and their three grown up sons are grief-stricken and have even called in their rabbi to say some prayers.
As they all huddle around Morris's bed, Morris suddenly asks, in a croaky voice, "Is my eldest son Avrahom here?"
"Yes dad," says Avrahom, "I'm here."
"And is my son Joseph here as well?" asks Morris.
"Yes dad," replies Joseph, "I'm also here."
"And what about Lionel, my youngest son," asks Morris. "Where is he?"
"I'm here dad," replies Lionel, "I'm standing right next to the bed looking at you."
"Well," croaks Morris, "if Avrahom is here and Joseph is here and Lionel is here, who's minding our store?"
