In the UK is it acceptable for a lecture/professor to join student societies?

Student societies are often fantastic fun. At the university I attend there are some members of societies who don't attend the university, they just come along because they happen to like an unusual hobby (Quidditch, table top rpg, fencing...). I have never seen any lecturers or professors however.

Is it considered odd for a lecturer or professor to be part of a society of their own university? Why? Would it still be possible? I would like to work in a university (in a research orientated position) and if there was no serious disadvantage or barrier I would defiantly want to be part of societies there.
