I seem to remember a guy catching cockroaches with beer in a cockroach trap - but it could be a figment of my imagination - like the time aliens came and started a folk club.

some people shampoo themselves with it.

some people sell it, others buy it and make it.
then there was the very fat man who watered the workers beer.

then theres Phil Beer, and Beer in Devon - so you can name places and people after it.

then you pour it down your pyjamas and play with a yo yo, but this is irrational behaviour and I do not recommend it.
