I just bought Halo: Reach and in my third match online, a couple guys were screwing around with a warthog. One which I was the gunner of. I thought they were going to drive off a cliff and suicide, so I bailed out, then he stopped and the guy in the passenger seat (presumably his friend) got out and got in the gunner seat. I realized it was a trick so his friend could get in the gunner seat (his friend tried to get me to get out earlier, prior to the clip). What happened next, well, see for yourself:
