L-Tryptophan

Three Turks walk into a bar and one says to the bartender, "I'm feeling sleepy from the full meal I ate during my holiday celebration."
The bartender, (C)arl, looks at the first talking Turk and says, "There's plenty of hotels in the area if you need a place to sleep."
At this point, the second Turk steps up to the obviously Armenian bartender and says, "Yeah. You know what it's like to sleep, don't you?"
The (o)bviously Armenian bartender turns to Cindy and says, "Whoop-La-La!"
All bets are off for the rest of the evening.

Take a (T)urk to June Lake. Bad fishing beats work!
