Ok, I'll take the bait. There is actually some great German comedy and a few super comedians (although you might find some of them under different labels such as satirist or political cabaret). However, none of them are really known outside of the German speaking world, for obvious reasons. Those, who have ventured abroad and tried their luck in English, have failed miserably and rightfully. Comedy is usually married to the language and always to the culture. Some of the most popular English humour is not very funny to me as a German, because it pokes fun at a culture that doesn't exist for me.
To throw a name out there, one of my German favorites is Loriot, same period as Monty Python. He did Rowan Atkinson stuff before Rowan Atkinson.
But, to keep things in perspective, yes, the Scottish bistros comparison works. But those 15-20 are really good.
