Mine is silly, I was watching an episoe of Frasier a couple of months back and it was the one where Daphne goes into labour at the vet surgery. There was a woman there with her monkey who was a nurse and offered assistance.
After Daphne gave birth, the nurse asked Niles to hold her monkey for her, he has the monkey in his hands jst as Frasier, his his Dad (John?) and Ros appear, Niles says "Oh, glad you could make itm but she's already given birth", at which those 3 look at the monkey and then Niles.
I don't know why, I found it hilarious, so much so that my stomach ached with laughter.
Hey ho LOL
