Reminds me of a bug I encountered once while playing Ocarina of Time as a kid.
I had gotten to the point where you meet Zelda for the first time, but before approaching her to start talking to her I was just messing around (looking in the windows and rolling around).
I ended up doing the z-targeting thing and when it targeted Zelda it glitched and the targeting reticule was focused lower on her, around her ass, and the A button option changed to "grab".
Essentially a bug was giving me the option to grab her ass.
It wasn't suppose to be that way, and a good deadpool is lol random. Its suppose to be a very thin line of logic clouded by stupidity and funny stuff. For Instance, in the game there is this part where before he starts a mission he blows up a bouncy castle full of air. a bad deadpool would laugh and say look at me am I random enough yet. But a good deadpool makes a quick joke about it, runs head first into the enemy base, and makes you forget about it through sheer violence and stupidity, and at the end, ends up using it to escape. its a rather lackluster example, but you get the point.
That edgy behavior is pretty stale and boring to a lot of people, and under normal circumstances it wouldnt be appropriate. The joke only works because deadpool is so silly and random. Oh wait, it doesnt.
