Q: How do you change the glass in a car window?

A: Brute force and a hammer. If you don't a hammer, use whatever you have at hand,  a rock or a bowling ball or a small wooden badger.

See? that wasn't so hard.

Why are you crying? Why would you need the cops? I changed the glass. There used to be glass. Now there's no glass. Change.

Oh. I see.

You meant "replace." Maybe you should be more careful what words you use when you shout at a homeless man carrying a small wooden badger.

Well it sounded like shouting to me.
