In the series Frasier, Noel Shempsky is a huge Star Trek fan. Now, the character of Frasier character is played by Kelsey Grammer, who also played Captain Bateson in Star Trek: The Next Generation episode 'Cause and Effect':
As I've mentioned above, these two characters are played by the same actor. Although in Frasier Dr Crane isn't an actor (and isn't playing Kelsey Grammer), surely Noel would still see a huge resemblance.
My question is then: does Noel ever comment that Dr Crane looks a lot like Captain Bateson?
