Where does bumming occur
in The Shining?

Sorry, I haven't seen it for a few years now, but I'd have thought that would be the kind of thing I'd remember...

You missed one
Human Traffic. the bumming scene when he's working in the shop was so epic it made my tonsils ache.

The Shining
The bumming in The Shining is somewhere towards the end. Jack Nicholson has gone mental and he opens the door to one of the rooms - and the barman is sodomising someone wearing a mask, or something.

Nah, no bumming in The Shining
It's a man in a bear suit performing fellatio upon another man. No bum hole penetration I am afraid.

^^^
You're right, strangely enough there was an advert on More4 for it last night, and they showed he fellation bit. Otherwise I would have sworn it was bumming.
