As the title states: What are some strange things you've done in games, or while playing games?

Skyrim is a great game for this.
For example, in Skyrim I like to pick up interesting things and arrange them tastefully in my house in Whiterun. At one point I had 3 Statues of Dibella sitting nicely on a shelf all facing the same direction - unfortunately the game erased them at some point.
I also made a point of collecting the Glenmoril Witches' heads and then hiding them in places around my house. I currently have one sitting on a plate next to my bed and another cooking in the fire under the cooking pot.
Another thing I did in Skyrim was TAI an entire town whilst they were going about their daily business. The town suddenly felt a bit... creepy.

In Deus Ex: Human Revolution sometimes I would confine myself to using only vending machines as both cover and a weapon. I would drag the vending machine with me wherever I went, whenever possible. Also secretly punching out people who I disliked on the streets.

In Shadow of the Colossus I would always jump off my horse and shoot lizards, even the ones who don't give you anything for doing so. I also wasted a lot of time trying to shoot the doves around the altar at the starting area.

Err.. Shoving a broom up a guard's butt in Skyrim.

Tried the glitch on 1:1, can't do it

In Oblivion, I held a basket in front of my face and deflected enemy arrows.

In LoL, I bought five Phantom Dancers and Boots of Mobility on Teemo. The fact that we actually won is depressing.

Beat up Proffessor Genki for an hour using the Penetrator in Saint's Row the Third.

Right in his stupid face.

Backflip with a jeep in Battlefield 1942.

Also. In oblivion i never wore armor or cloths. Not sure why, but it worked fine.
