Sketches (perhaps in conection with Sherlock Holmes?)

Hi!

I'm searching for a site where I can find sketches. Either if it's instructions or texts - it should be funny and performable for a group.

I'd welcome it very much if you linked me to such a site; or, if you remember the main idea of a sketch, just to write it down.
And it would be great if you knew some sketches about Sherlock Holmes and/or his dear friend Dr. Watson.

Thank you very much in advance!

Regards,
Alexander
