Ok so I found this one on accident a long time ago and just tested it and it still works. I'm a pally, and I haven't tried this with another rezzing class so I'm not sure it will work for another type of rezzer.
Anyways, have a hunter put his/her pet on defensive and stay, and start the duel. Make sure the hunter forfeits the very second his pet dies, and then IMMEDIATELY rez the pet. If you did this right and your timing was dead on, his pet should now be following you instead of the hunter. Might take you a few tries but it definately works. There isn't to much point to this besides something to laugh at, but I figured I'd throw it out there.
