I was playing against my brother me with Ganon and him with Link, he threw his Gale Boomerang, so I jumped over it, landed on the ground and used side b as the boomerang was coming back. So it carried us off the stage and he couldn't go far anough to recover, but I could. It killed him at 0%.
Another one I was using Falcon Punches only in a random wi-fi match, the match went to sudden death, one person got killed by another guy. Next I Falcon Punched that guy, and then I beat the other guy with another Falcon Punch.
Once with Peach my friend was playing Wolf and tried to edgehog my Peach so I hit him with the umbrella on the way down, and I opened and closed it over and over and he couldn't get out.
Using Dedede and jumping off the stage with Dedede using Jet Hammer and shoot them off the screen. So epic!
Oh yeah, one of my favorite things to do in Brawl. Pick Jungle Japes with Donkey Kong and stage spike someone on the right side of the left most platform. DK survives, but they don't! lol
