Why should you never fart in an Apple store?
Because they have no Windows!
Listen up, buttercup. This joke is all about that wordplay. See, "Windows" is a computer operating system made by Microsoft, but it also means the glass thing you look out of. Apple stores don't have the Microsoft Windows operating system, so the joke is saying they don't have regular windows either. Get it now, dummy?
name doesnt matter
you should also just let steve jobs do this job.
