'most of these jokes are anti-insertwhatyou(don`t)like....'

well I disagree.

The telephone box one

By and large we ARE a nation of servile lickspittles. look at all the bottom kissing that goes on when an 'important folkie' drops into the mudcat.
Look at the fact we consent to be governed by graduates of Oxford and cambridge Universities (no matter how stupid) - both political parties have cottoned onto that.

the 'under the soap' joke

Fair number of mingers in any collection of Brits. You know what they say 'poms don't tub'. It goes back to when we had poorly heated houses and it was very cold - too cold to bath really. Before and during the war there so much BO about, that cinema audiences had to be sprayed with perfume.

the Noel coward joke

when I first heard it, the journalists said - say something Australian Noel, and Noel enuniciated KenGahroo!

Yeh! posh people do talk funny - particularly our theatricals.

the Pom jokes are quite a good dig at our national character.
