Can't remember too many things off the top of my head, but you reminded me of something...
A nooblet quite a bit lower level than any of my friends began to follow us while we were in Ardy as we were prepping to go out pking or something like that. I said I was going to vid everyone, so he said "OMG can I be in your vid?". We didn't know the kid, and we thought he was getting a tad bit annoying, so we decided to invite him to come along. He followed us out the lever and a bit to the east of the Mage arena. I said 'Hey (whatever his name was), you're on vid now!', and the lowest level of us kicked the snot out of him with Ancients + Whip. He wasn't exactly happy, but we were all laughing

.
Reminded me of another time two other friends and I were out with junk items at the Obelisks PKing. A level ~95-ish with 99 Range thought we were doing alright, and he didn't want to get killed by us, so he decided to ask us to team up. We were all on the phone, and decided this was going to be 'fun' considering he had just gotten a Dragon Scimitar and was currently using Dragon Bolts (e) to get kills. We decided to hop, but we told him the wrong world. When he switched back in, we all Speced him out, and got a few other hits in. He wasn't exactly prepared

. We saw him a few times after that, and he never did get his revenge. One of the two friends even saw him while he was junk-pking by himself, and he killed him again with Bone Bolts and a DDS.
