I love 'Curb Your Enthusiasm'. That doesn't mean I want stereotype humor here – unless it can be artfully deployed to add some unique new insight. (Many others don't grant even that exception for referencing stereotypes.)

Also, CYE's humor is way beyond recitation of cliched stereotypes; common knowledge of stereotypes is the setup, not the punchline. Usually, Larry's elaborate mishaps while trying to escape, reverse, or disavow stereotypes creates the humor.

So perhaps if you now go through comically absurd lengths to prove both your religious sensitivity and your essential loyalty to The Tribe, but fail miserably so that by the end of the episode everyone is against you – then you can use the "I'm just like Larry David" defense.
