For the record, I believe all of this, hands down. The reason for that being that I've gone through a few epically-funny situations of similarly incredible proportions. I will give examples...
EXALTED - You all know this game, right? You play as people who are super-capable in so many skills that the point is to do things as impressive and flashy as possible in a fantasy realm. I was playing in this with some friends and...okay, lemme just describe the setting. Enclosed room full of bandits. Several of us are fighting. My colleagues began to edge out of the way as another in my group was about to cast the "Wrath of Obsidian Butterflies" spell. Basically, a huge swarm of obsidian blades would shoot out into the room and there weren't many hiding spaces. Since I was in the middle of the room, but had the most versatile character, I decided to pull a stunt where I leap from cover to cover (i.e. I used bandits both living and dead as said cover.) to get over to a safe spot. Brilliant idea in theory, total failure in practice. I botched the roll horribly and tripped on my own feet. Funnily enough, the hit dice for the spell that was about to cut me to ribbons and was unavoidable now ALSO botched horribly and so I was not hit. The reasoning behind it was that the nearest bandit fell on top of my and I ended up having to clean the guts off afterwards.
STAR WARS - Okay, I'm not the most avid of fans to the series, but I like it enough to give it a shot when I'm bored, and I have a friend who GMs this stuff very well. SO...my group is a smuggler/courier crew on a ship with enough upgrades to rival most in its class and beyond, and we have just found...an old adandoned trade federation military drop vessel...which was to contain something we were suppose to recover for the job. Unfortunately, it's got active - though drained - battledroids. You know, the "Roger roger!" guys. Well, we come upon a squad of them and pretty much mop the floors with 'em. Then my captain takes one of their heads and uses it in a deception for the next group. He holds up the head, says "He said we could go past.", pointing to the head, and then mimics the droid voice going "Roger roger!" and waggling the head around. This ACTUALLY WORKED, and - to make a long story short - we were able to commandeer the vessel and everything in it, tanks, troops, and all...though I had to reprogram the droids. (Hey, I was the only one who took the trade federation language, and you have to end all the command taglines in "Roger roger!".)
So yeah, I buy it. All of it. RPGs are all about the funny stuff you can make happen.
