It made my day

I am not an evil person, in fact, I'm not even moderately mean. But I do enjoy watching somebody else making a total ass clown of himself. And it's even better if I can help them along in any way.
See, what happened was this: I was driving on a three lane highway in the middle lane. This was fine because I wasn't going too slow, nor too fast. I wasn't in any particular hurry, so I was driving precisely the speed limit. I'm driving a little Toyota (my parents' car) and this huge, gleaming white SUV with a custom hood ornament starts tailgating me and flashing his brights in my rear-view mirror (it's angled just right so that the glare goes straight to my eyes).
I look back and there's this major douchebag behind the wheel making motions for me to go faster.
I don't understand his problem. There's an empty lane to the left, there's an empty lane to the right. There's even a notorious speed trap around the bend, and as I previously said, I was going exactly the speed limit. So to annoy him I slow down a little bit. Nothing noticeable, maybe 3 mph, but this guy is so close he almost rear-ended me. Now he starts to honk. I make a big show of ignoring him (easy to do while facing forward and wearing sunglasses).
Well, he pulls into the left lane and speeds ahead, giving me the finger as he speeds by.
I'm a little pissed off, but not much, he's a moron and a jerk and taking it out on the world. Not my problem.
Anyway, a few miles ahead the traffic slowed to a crawl. The three lanes were funneling down to two because of some kind of roadwork.
Well, Mr. SUV passed me on the left, and I saw him stuck there ahead of me. His lane wasn't moving and mine was. So, he of course pulled into my lane ahead of me. I beeped the horn friendly-like and when he looked up I smiled and waved at him, as if we were best buddies.
I swear the guy turned scarlet. I mean, there is nothing worse than acting all friendly to these jerks, it really gets to them.
By now our lane had stopped moving and now the right lane was moving again, so he pulled into the right lane and took off.
Ten minutes went by, and I kept creeping along in traffic. I didn't mind, it was air-conditioned and I had some good tunes with me. Needless to say, Mr. SUV was long gone.
Finally I get to the obstruction, and I see that the right lane was blocked off. There weren't any cops to direct the traffic, there was just a huge sign saying that the lane ends because of road work. The people just merged the best they could.
Well, I saw that there was a familiar looking SUV stuck in the right lane behind the orange road-work sign, trying desperately to merge with the middle lane. But since traffic was at a near standstill, everybody was close up against the car in front of them. There was nowhere to merge.
I laughed out loud, and when I drove by I beeped my horn again and waved at him.
Man, was he pissed! He jerked the wheel to the left and slammed the gas, trying to cut me off.
Unfortunately he forgot how close he was to the warning sign.
He drove straight into it and the thing fell over and smashed his hood. His custom hood ornament was destroyed, and the whole hood was scratched beyond belief. No actual damage to him or his car, just his poor, over-inflated ego.
It made my day.
