I got a call today on my cell.  Conversation goes like this:

Caller: “Is Len there?”

Me:  “You have the wrong number.”

Caller: “Oh!  Is his number 555-555-1234 instead?”

Me: “Well how the heck would I know the number of the person you are trying to call?!?!?!”

Caller: “OH! I must have the wrong number!”

Gee, who woulda thunk?
