3 operating systems walk into a bar
The first says “I’m Windows. The most popular, everyone likes me and I don’t mess about. I’ll have a pint of lager.”
The second says “I’m Mac OS. I’m the favourite of artists and hipsters, and I could never settle for a boring lager like Windows. Give me your hoppiest artisanal IPA!”
The third says “I’m Linux. I’ll have some water, hops, barley and yeast please.”
