A String Walks Into A Bar

He says, "hey bar keep, I'll have a beer". The bartenders sternly replies, "we don't serve strings here". The string walks away discouraged.
He comes in a few days later and tries again, "hey bar keep, I'll take a rye". The bartender, more aggravated replies, "I told you, we don't serve strings here!" The string leaves disappointed.
The string figures he will try again a few days later. He walks up to the door of the bar and thinks for a second....This time he ties himself in a loop and messes up his hair. He walks up to the bar and says, "hello bar keep, I'll have a rum and coke". The bartender replies, "hey, aren't you a string?" The string replies, "no, I'm afraid not"
