Skyrim: I killed two druagr and they fell onto position looking like they where hugging one another.
Team Fortress 2: I watched a Soldier rocket jump and on his way back down, an enemy soldier rocket jumped right next to him and slammed him down to earth with a shovel. I was like daaaaaaamn.
Portal: I did not feel bad about the companion cube at all. Mwahahah
Zelda Ocarina of time: Every single time I teleported with the songs.
I enjoy doing stupid things in Just Cause 2 such as attaching boats to planes and riding in them as they planes take off or attaching a soldier to a wall and watch him struggle to get himself out or just causing pure havoc around the city.
