funny music

Remember that some time ago I wrote a little post about what makes it the case that one can make humour from speech, from visual elements, but hardly anything else such as taste or sound. well thanks to Caz this piece is very close.
these two guys cleverly mix pieces of music that you wouldn't normally associate with one another, which creates a kind of irony. the ending is particularly humourous because they takes just about all the different kinds of endings from classical music and make you think that the music is going to end but it never does.
