Well as you know I've been watching a lot of Red Dwarf lately, and it's an awesome piece of British comedy. It was a bit hard finding single scenes or clips that could be funny without the context of the rest of the episode, so if you've never seen it I would have to suggest checking it out.
The first video is a scene in which Rimmer, one of the characters (obviously) is on trial for committing the crime of causing the death of the entire crew. That's not really a spoiler, don't worry. What follows is by far the best legal defense in history.
The second clip is from an episode where Kryten, the robot from the above clip, is turned in to a human, and is having a little trouble adjusting to his new body. Apparently Craig Charles, the actor who plays Lister, was given an actual picture of a wang just to get a genuine reaction.
Like I said, it's a great series, easily worth checking out.
