If he's got a solid sense of humour, "Allo allo" will do nicely, sending up English stereotypes of all Europe (including the English!).

Blackadder 1 was very average, and Blackadder 4 was the Rowan Atkinson Show. 2 and 3 are the ones to go for. And for other NTNoCN residents, there's "Alas Smith and Jones".

Don't forget "Red Dwarf". But avoid anything else with Chris Barrie in it.

"Gimme gimme gimme" was good if you like that kind of thing (which I do).

And for a different flavour of "British", there's "Goodness gracious me". Doesn't always work for a white audience (sometimes there's stuff that just vanishes over my head with a whooshing noise), but some of it is very good, and it's very much in the spirit of English comedy.

Further afield from England, there's "Rab C Nesbitt" (might need subtitles! :-) and "Father Ted".
