The English respect only two other types of humour, besides their own: the Russian and Yiddish.
Thats because they don't like people making laughs at the expence of other people.
They prefer people making laugh of themselves, otherwise it is a bit sadistic, in particular when peple of power (like the POB) laugh at their subordinates.
Maybe Scott secretly adores POB - he supplies some punchlines for him lately.
