Saw a music video on beavis and butthead..can you help me figure out what it is? sorta freaked me out?

ok it had this weird little midget or a little girl and 3 guys who were hitting a barrel with these metal things, (chainsaw, giant hammer, and something else i think) and sparks were coming out, then the girl saw a piano and said "HEY!" and they came over and smashed it, and they did the same with a violin. she keeps yelling HEY! through the whole thing at the beginning butthead said..hey beavis, that little girl just took a dump (or something like that). it kind of freaked me out so i was wondering if anyone could help me figure out what the heck it is. thanks
