I'm willing to claim that it's "easy" to be really good at a game. That is, no scopes and multikills and what have you litter Youtube. Everywhere. What I want to know are all of the times when all of those random circumstances happened to line up for you in such a way that just couldn't have been planned or gone better.
One of mine would have to be during a game of TF2 when I was on turret duty. You know. Protecting the intel. A guy on the other team has been killed by my turret before, and doesn't realize he's on an open channel. He tells his team he's going to "just disguise himself as one of the engineers down there and grab it." The moment he walks in I lay into him, and both teams spent the next 3 or 4 minutes explaining to him that we could all hear everything he was saying.
Well, I once got five crits in a single Icicle Spear in Pokemon White. It hits 2-5 times (I got all 5 hits, which is 18.75%? odds) and a crit has a 6.25% chance of happening per hit.
On the opposite side of the spectrum, I got 23 consecutive Hydro Pump misses before one hit. Hydro Pump has 80% accuracy.
When I beat a certain boss in Dark Souls. It was the one with the two guys: one had a spear and the other was fat and had a hammer. I killed the fat guy first and then took on the giant powered-up spear guy. Then I got the material to make his spear but unfortunately it kind of sucked. Supposedly it was easier to kill the spear guy first and the fat guy second but I wanted the spear more than a hammer. It took some tries but it was worth it. Good boss fight IMO.
first time playing strange journey, beating a boss in that game, for a good 5 minutes I was jumping for joy, at the level your at the boss hits stupidly hard
The day I met my first true FFXI friend. We were both noobs that decided to team up to make the game somewhat easier on ourselves at the beginning. We hit it up pretty good and we basically became inseparable.
One day, playing Dynasty Warriors Gundam 3. Destroying the Black Tri-Stars (all three at the same time) with one SP Attack using Duo and his Deathscythe Hell. I couldn't believe my eyes. And no, it wasn't intentional.
Playing God Of War 3 on Titan and got to the three headed Dog boss and for literally 4+ months I couldn't beat the game, then one day I picked the game up and wrecked everything with a vague plan in order everything just fell into place and I was yelling and running around the house and almost bust a few tears. I beat Zeus and the rest of the game in the same day.
While playing Modern warfare with my friends (via LAN), I accidentally threw a grenade. I ran for my life, then suddenly it told me that I killed 2 persons by accident ^^
#1 - Beating Alex Valle in Marvel vs Capcom 3 (He's one of the best Street Fighter Players) with hardly any effort. Couldn't believe it.
#2 - Beating Viscant in Street Fighter x TEKKEN (He was the 2011 Marvel vs Capcom 3: Fate of Two Worlds Evolution FIghting game champion) and got the YouTube proof for it.
#3 - My little sister getting her own Xbox and learning how to play Geares of War just cause she thought I looked cool on the headset playing and wanting to do something with me.

YESSSSSSSSSSSSSS!!!! freakin' Ornstein and Smough, i danced a victory dance of epic proportions when i took these guys down (IMO one of the BEST boss fights in the game) XD
Beating Lu bu during the Hu lao gate battle in dynasty warriors 4. When I was a child I always freaked out and ran like a pussy when I saw him. now I'm more like "PSH just another enemy officer to mow down"
Oh and finally beat Zinaida on Armored core last raven. for some reason she gave me more trouble than the secret pulverizer boss
That Ornstein and Smough fight will be remembered for quite a while.
That one aside, I remember beating the last boss on Metroid Prime 3: Corruption on the last 0.5 seconds. What makes this even more memorable is the fact that I was the one aiming since the game used motion controls. His weakpoint was quite small and he had enough health to survive one charged blast. It didn't matter though, in the edge of the moment I charged my shot and aimed by instinct. I swear, I even shouted "GOOOO!!!" when I fired it. My God, when that blast connected, the boss was beaten. I just couldn't believe it, it defied game logic and yet it happened. I had a smirk plastered on my face for like ten minutes. I'll always remember that feeling.
I don't know if this counts as a game game, but a few of my friends and I went bowling one time. During my frame, I released the ball, then turned around and got on one knee, then slowly sheathed a pretend sword. When the "hilt" hit the "sheathe," I got a strike.
