I went to a hamfest (an electronics swap** meet) last sunday, a week

asked a guy at the table with those running the thing if it said "One
A.M." or "I am". He said it meant I am. I said, what does that mean,
and he said it meant "You are".

Does anyone have an idea what it really meant?

Almost surely "one a.m.", and the lad was having a leg pull.
