Yesterday I put up a recording of Canadian comedy troupe The Frantics' well-known routine about the alleged martial art 'Ti Kwan Leep'. It appears to have been well received; there are lots of people coming here from the Internet and going straight to it, meaning the direct link has been passed around.
What I didn't know, but some commenters pointed out, was that this wasn't the first appearance of the 'Boot To The Head' line. That, apparently, came in an earlier sketch titled 'Last Will and Temperament'. Fortunately, YouTube has a recording of that one as well.
