What about them crossdressing Brits?

Why do the British find it so funny when men dress up as women?

If you don't know what I am talking about, watch ANY British attempt at comedy.

I don't understand why you think it's so popular. Perhaps you could name a few of the series where cross dressing takes place. Little Britian is one, but I can hardly think of any other series. Like >>2 pointed out, there are many series like The Office for example where there is no cross dressing.
