The only problem is that when I watch it in the original, I don't understand all of it. And when I watch it in German, a lot of the humor is lost. But yeah, I'm going to start it in the next few days.
A few of their jokes are with language puns. But not many.
Most of their jokes require general knowledge and history, than language knowledge.
And although it's very silly humor, it's also very intelligent.
For example, one of the best jokes in The Holy Grail is the "Your mother was a hamster and your father smelt of elderberries!"
It's funny by itself. But if one considers that at one point in history, these were real insults. As in hamsters reproduce a lot. And poor people in mediaeval times, made wine out of elderberries.
So this is an indirect way of calling someone's mother a whore, and the father a drunkard.
