Memorable ridiculous moments in games

In the wake of Bayonetta with all its nonsense action, what are some outlandish moments in games that you remember? One that stands out in my mind is suplexing the moving ghost train with Sabin in Final Fantasy 3. Quite an impressive feat if ya ask me.

Uncharted 2 

In San Andreas, killing the guy with the dildo and wearing the gimp suit. Still sticks with me to this day.

Super Mario Galaxy, when I realized that I was playing a game about an Italian plumber eating psychedelic mushrooms, transforming into a bee and jumping between tiny and extremely strange-looking planets, all in order to rescue a princess from a fire breathing turtle who plans to conquer the Universe. 
 
The ridiculous part was that I hadn't questioned it for one second. 

Persona 4. I don't need to explain. Yes I know I know but seriously, I've all the games I've ever played that one was just, what?

Modern Warfare 2
 

Pretty much all of Shadow of the Colossus

*insert moment from Modern Warfare 2 Campaign here*

The tower dive from Devil May Cry 3.
 
Damn. Just......damn.
 
Also, in Army of Two: TFD, when Salem (kinda out of nowhere) points at a poster of Jonah and says to Rios "I want to kill him". Rios' response? "Let's do it". They then set off to kill him. So awesome and ridiculous.
