Never mind milking the bear - I'm confused how one can even birth a cheese.
For learners who may not be following the jokes - Dave and I are playing on the various meaning of the word 'bear'. This is all result of the slightly unnatural phrasing of 'I can't bear cheese'. Saying "I can't stand cheese" would have removed at least some of the opportunity for word play.
Note we could still jest about cheese standing as opposed to sitting.....
