Selection Mistakes

A sentence in which 'concepts are put together in impossible ways', but are otherwise grammatical.

Examples (from Hodges):
i) The pianist then played a red hat topped with geraniums and wisdom.
ii) He ate a slice of boredom.

Challenge: compose a short dialogue in which every sentence contains a selection mistake.

I find it surprisingly difficult, and note that there seem to be two main types of mistake:
i) combining things from the mental realm with things from the physical realm (John accidently sat on his good intentions) - when read literally, these statements seem to contain logical errors
ii) making ridiculous combinations of things from the same realm (John filled up the balloon with Wales) which are logically possible, but not all that likely
