RE: Katey!
PAINTBALL. NOW.
Seriously, nothing's more fun than sprawling out in wet mud, taking potshots at a fat guy stuck in a van. Well, except joining the armed forces and taking potshots at militants stuck on camels or something, but that can also be life-threatening, and that's not really all so fun when you take that sort of risk into consideration.
Anyway, paintball. Yes, do it. Just don't take the ****ing mask off, else you'll end up like that kid that I did NOT shoot in the face*. I've been (on average) once every year since 1999, and it never gets old. Of course the big downside to paintball is that you WILL get filthy, and by the end of the day smell of chemicals and ****. But then that's what home showers are for.
If you want to really enjoy it, go with at least a couple of friends, but keep your group small-ish. It's more fun when there are 3-5 of you, and the chances of being separated and put in different sets are smaller.
As for bungee jumping, I won't deny it's a lot of fun to free-fall for those few seconds like that, but it's over in literally no time at all and costs an absolute ****ing bomb. Then there's the waiting around for your turn, although the plus side of this is seeing the cowards come back down the lift and take the walk of shame out of the area and back home, where they slit their wrists or (in some sort of ironic twist) hurl themselves off a building.
Been off-roading too, it's nothing to be terrified of and is actually fun stuff. They allow unlicensed drivers for a reason; nothing can go so utterly wrong that you pull a Rik Mayall/Ozzy Osbourne and somehow find yourself under a quad-bike. At worst you'll get a jeep spraying water all over the place while spazzing the steering wheel around trying to find somewhere to get grip.
*I shot him in the nuts through the gap in a pair of barrels (pure fluke), causing him to stand up and get shot in the face by someone behind me. THEN he took his mask off... and got shot in the face again by someone else. His scream lives with me to this day, and it makes me laugh. What a moron.
"It turned out that the ghost was just Mr. Finley, who ran the amusement park. The spooky part is that, as soon as the ghost appeared, the teenagers' dog began to speak! And it spoke in a tortured parody of human speech: 'relp me, Raggy,' it would say. 'I am an abomination and rould re rilled. Rill re, Raggy.'"
