And now here's Xander Harris with "The Bum Bum Song"...
To the tune of "The Bum Bum Song (Lonely Swedish)" by Tom Green
altered lyrics "The Bum Bum Song (Lonely Demon)"

My bum is on the vamp, my bum is on the vamp!
Look at me! My bum is on the vamp!

My bum is on the Watcher! Buffy's watcher!
It's a lot of fun to put your bum on a watcher!

My bum is on the grave, bum is on the grave,
Don't fall down on the gave you might hurt your bum!

And that's not very fun, if you fall down and hurt your bum,
I like to put my bum in things, its fun for everyone!

My bum is on Oz! My bum is on Oz!
If I get unlucky, he'll bite me in the bum!

My bum is on the Demon! Demon!
Demon...demon.

My bum is on the stake, bum is on the stake!
I can kill a vampire with my stake, stake, stake!

My bum is on Buffy! My bum is on Buffy!
I hope she doesn't shoot the crossbow in my bum,
and shoot poo all over the place! Poo poo!

And that's not very fun, when she shoots a crossbow into your bum!
I like to put my bum on things, its fun for everyone!

My bum is on the witch!
My bum is on the cross!
My bum is on the ghost!
My bum is all alone.

The vamp, is all alone.
The Watcher, is all alone.
The demon, is all alone.
My bum, is all alone.

1...2...3...4

My bum is all alone,
My bum is all alone,
My bum is all alone,
My bum is all alone...
