Teams are definitely where the craziness is at, whether it be good or bad...
Somehow, Tar and me (Same guy I accidentally rollout'd on my team) almost won in a teams vs. people who actually knew what they were doing... Me (Jiggly) and Tar (Samus) vs. Yoshi (Jiggly) and I forget his partner (Shiek). Round two, we picked Kongo Jungle... managed to get a rest off on the Shiek, and I'm like "Yeah! w00t, I rested a superior player!" only to realize I did it over open water. Ouch.
And at the end, it was 1 & 1 vs 1 shiek, I think Yoshi might've got the klap... Tar didn't know that Yoshi had died, and kept attacking me, thinking my Jiggly was Yoshi's Jiggly. Once we sorted out that Yoshi had died, in comes the shiek for something like a ftilt to fair to kill the samus and leave me all alone vs. him...
I've had my share of dumb moments, like rollouts missing the stage. But I've also had my high points, such as jumping into a brawl on the right side of FD, having my partner roll out of there just before resting both opponents... those moments are sweet.
Oh, but speaking of crazy kills, I don't know if he visits SWF so I"ll post it for him. It was FC6 I believe, little Paul vs. Eddie the ganondorf, him as Luigi. He had a cast on that day, so it impeded his playing. As the story goes, he was going to downsmash Eddie's ganon, but didn't press the control stick far enough and ended up down tilting the ganon, popping him up in the air. He jumped to fair him, but his finger slipped from the A button and instead hit the B button, resulting in a misfire that killed the ganon XD (He went on to almost win that match; ganon was in the process of being star ko'd when he hit the edge of the death wall... afterwards, Eddie took off his headphones and said to him "**** you.")
Oh, and another one I just remembered, even if it wasn't a KO, it's pretty dang funny... don't remember who I was facing, fairly sure it was FD, but I was IC (think I might've been facing a fox). I was either just knocked away or in the process of being star ko'd, when Nana, on her own, goes and smashes my opponent out off the stage, followed immediately by a taunt. Whether that was a KO or not, I'd say that's glorious :D
