The Box. That is all. Also a fabulous Joel moment.
Fair to say Joel gets the highest amount of funny out of the cast.
Switch. Only Rooster Teeth could take the lamest, clichéd jokes in history and make them funny again.
In Unusual Suspects, their is a point where Gus (in a police uniform), rounds up Jason (dressed a Construction Worker), Matt (dressed as a Cowboy), and Nathan (dressed in chaps and leather). If you havent't gotten the joke by now, here's one more for you, they find Kerry doing graffiti, they grab him and throw him in the trunk of the cop car, and before they close the trunk on him, they toss in a native american headdress. Yes, you read this correctly, they are driving around in a cop car, dressed like the Village People.
That's not even the best part. When they throw the head dress in for Kerry, they all have these Serious Business looks on their faces. It helps that a Braggadocio rap track is blasting over the video.
Matt's Squick reaction when Joel drops what is strongly implied to be a human penis in his ice bucket during the hotel episode.
Heck, any of Matt's reactions in that episode. The instant turn from "You are a god" (hearing two girls in the room) to "oh God no" (hearing two girls and what sounds like a very large, probably very hairy man in the room) is priceless.
The revelation that the people who apprehend Joel for not playing Kinect are... the TPA.
The Mega 64 collaboration episodes in general.
When Jon CJG arrives at the office, he is mistaken for Gary Busey, and then for Nick Nolte, at which point an angry Joel throws him out.
Coasting... well basically, Gus is... on a roller-coaster, and at the same time at the desk directly behind the guy he is apparently talking with... this is one of those things that makes less sense in context.
In the one they made to celebrate their tenth anniversary, Gavin basically ends up parodying himself with English slang that makes no sense. It's made priceless by the completely deadpan way he says it.
Made even funnier if you know what he's actually saying, since he's using rather filthy slang.
Gavin: There was spiff all over his quaff, it was mental. Alright, knob and bob, tosser.
