In the episode, called “The Celebration Experimentation,” Leonard and his pals convince Adam West to attend Sheldon’s birthday party.
If Adam West has originally had his way, it might have been a Rottweiler or two who risked going crazy.
Adam West played a fictionalized version of Adam West — as he did with surprising frequency — in his appearance in the big milestone 200th episode of The Big Bang Theory, and he evidently had notes on the script when he first read it.
West agrees, but he asks Leonard not to ring the doorbell, lest his pet poodles go nuts from the sound.
