Enslaved: Odyssey to the West/Funny

After Monkey and Pigsy climb to the top of the ruined machine...

Monkey: So... How did you get a name like Pigsy?
close up of Pigsy's hog-like Power Armor.
Pigsy: Haven't a clue.
and moment's later...
Monkey: I'm Monkey.
Pigsy sniffs at the air.
Pigsy: Guess that one's obvious.
Pigsy walks off, and Monkey discreetly sniffs at his armpit.

Right when the main characters use an escape pod after their ship blows up They are all tightly cramped together, which leads to the following conversation:

Pigsy: "Um, Monkey, could please try to shift your left hand?"
Monkey: "I don't really see how I can."
Pigsy: "It's just that your hand is resting...right on my...penis."

- The expression on Pigsy's face is what really makes it so damn hilarious.
When Monkey, Trip, and Pigsy are inside the Leviathan

Pigsy: This machine is more amazing than my wettest dreams!
Trip: What did you say?
Pigsy: This machine is more amazing than my wildest dreams!
Monkey: ...That's not what you said.
