There are too many to count for me. I saved most of them as replays.
1st one, I was Game & Watch, opponents were Ike, ROB, and Olimar, on anyone wifi ffa brawl. We were on Hyrule Temple. There were two funny kos. For the first, we were all near the right edge of the stage. I used my judgement hammer on Ike towards the edge of the stage and got a nine, getting an instant kill on him. Then, after a delay on the nine, ROB jumps into it from the back and gets ko-d to the left off the top of the stage. Both were with the same 9, with ROB being kind enough to give me a free ko.
The second one in the same battle occured in sudden death. It was me (Game & Watch) vs. Ike. At First, we both did a taunt, him saying "prepare yourself". Then I started to chase him around the stage, as he ran away (coward...). So I decided to go to the bottom of the stage, right below the pathway from above, while he decides to stand on the pathway above me, with the roof above him. We both expect each other to just jump at each other, then the bombs start to drop. I begin side-stepping like mad, while he does nothing. The bombs don't go near him, while two bombs blow up right beside me as I was in a sidestep. After a while, I decide to jump up and do a forward air on him, thinking he wouldn't expect it. Right before I jump, he taunts "prepare yourself". Obveously he wasn't prepared, as I forward air'd him to his death. I then did my taunt over and over again.
Another funny (more lucky than anything) was in another wifi anyone freeforall battle. It was sudden death, with only me (Yoshi) and Ike left. This is a different person, not the same Ike as the last battle. So we begin fighting, and really go at each other (this is sudden death!) We both do strong attacks on each other and dodge them all (with a few non-fatal hits). Then he begins to charge a forward-b on the ground. I didn't see it and went for a neutral air right in front of him. He unleashed it right as I was in the perfect spot and knocked me off the screen by above. Just as he hits me though, the bombs begin to fall, and right after he hits me, one hit him without him able to defend himself. He flies off the stage to the side and dies before me. I got lucky.
Both I have replays for, along with others.
My funniest match would be with me as Game & Watch, against Pit, Meta Knight, and Mario on the smashville stage, on wifi free-for-all vs. anyone match. Everything was going well for me. I got 8 kills and didn't use a single life (+8). During the match, I got a nine kill (judgement hammer). Later, at 98% damage, a maxim tomato dropped right in front of me, with food right beside it, allowing me to recover most of my health. Later, I got a smashball (as if I needed more to go well for me), used the final smash, and got 2 kills early. I then chased metaknight (the only one I didn't kill as the octopus) and accidentally hit a smart bomb (huge explosion bomb) and metaknight gets caught in it right away. Then pit is smart enough to jump into it and they both die. That's 4 kills with the final smash right there. After that, time was basically up, so I went to the side and taunted.
+8 in a wifi 2 min battle.
I have many more, but it would take forever to post them all up.
