Season 2? I am trying to identify an espisode...

Hey guys!
I remember seeing an episode where two people were some place tropical and they had a fight with weird objects. Someone pulled out a monkey or something and started swinging the monkey around... haha, I don't know. Anyone know what I'm talking about?

I swear that it's in a different season, cause I've seen all the season 1s and I haven't seen it in there (or remember seeing it, at least).
