Kent, you're still the man man.
I would NEVER run along someones car.
Unless the person in it would have stolen my cash.
Or if it was Elvis.
If I bumped into Keith I'd probably say "Excuse me sir, I'm not bumping into you because you're The Keith Richards, it can happen to anybody right. I'm not hoping for a smart remark or for being told off in a typical way. Please don't think that."
