 Howard, what are you doing here? Sicking also was known for playing Doogie Howser's dad on Doogie Howser MD. He also had roles in Star Trek III, The Search for Spock, Fever Pitch, and Curb Your Enthusiasm. Someone got on and there was a young boy, I was nine years old, maybe 11 years old, and he looked in the elevator and he said, oh, look, it's Mr. Howser. And just as the elevator doors were closing, you could hear the mother offstage saying, Dr. Howser.
