Kitt telling jokes

[HungarianKnight]

I was just watching Dead of Knight (Season 3), in which Michael gets poisoned and his life is slowly fading away. Kitt is desperatley trying to keep him awake and is telling knock-knock jokes. Boy, those were lame, even in Hungarian (Okay, there was one that was actually good). Was this the only episode where Kitt was telling jokes? I remember Out in the Woord too, where Kitt adopted the accent of a New York Cabbie, that was hillarious too...
