From the Wikipedia entry on Northern Calloway, the guy who played David on Sesame Street:
Near the end of his life, Calloway slowly began to exhibit signs of bipolar disorder which led to a nervous breakdown on the morning of September 20, 1980 in Nashville, TN. He beat his hostess with an iron rod, damaging it and giving his hostess head and rib injuries. He then fled into the suburbs of Nashville. Along the way, he smashed a plate-glass window and storm door at one house and did extensive damage to the the interior of another, destroying the family's collection of fine crystal, smashing a television set and breaking light bulbs with his bare hands. He also stole a backpack from a first grader and smashed a windshield with a rock. He was arrested after hiding out in a couple's garage, screaming "Help! I'm David from Sesame Street and they're trying to kill me!"
Now watch Calloway and "Maria" in what must be the only Sesame Street segment with genuine sexual tension.
