Why do people say "for Pete's sake"? Who's Pete? Why does he have sake? Why do we need to do things for his sake? WHY IS HIS SAKE SO SPECIAL?

Well you know what? Forget Pete and his sake. I'm gonna think a bit more creatively

So I shall say random names/characters each time instead of Pete. So EVERYBODY'S SAKE CAN BE SPECIAL :D

Share the love, for Margaret's sake. (Don't ask who Margaret is)
