idea for dealing with bums...lol?

Alright, I had a crazy idea: What if someone could design some type of gun that would fire quarters. That way when I pull up to a freeway on-ramp and there is a homeless dude begging for money, I can bust this thing out and be like "READY?!!!!" and he'll take a swift inhale of air, drop his arms to his sides while flexing his chest and be like "okay! do it! GO!!!"

Pop! Pop! Pop!

Bum: "Thanks brotha!"

Me: "Woooooooo!" *tires screeching*

I think this would be a lot of fun and we would both win. What do you think?
