Sure why not? It only absolutely no sense whatsoever so hey in for a penny in for a pound as they say, this probably wasn't a coma but a bad acid trip on the other hand who knows? With how random the whole thing was Spike might as well have barfed up the Oompah Loompahs and knowing this episode they would have given them a song which probably would have gone something like this.

 

Oompa Loompa, do-ba-dee-doo

I've got a perfect marketing strategy for you

Oompa Loompa, do-ba-dee-dee,

If you are dumb you will listen to me.

What do you get when you drink the kool aide?

Drinking as much as a sailor on shore leave.

What your wallet is at getting terribly fat?

Who do you think is responsible for that?

I don't like the look of it.

Oompa Loompa do-ba-dee-da,

Let the writers do their jobs and you will go far

You will live in happiness too,

Like the oompa loompa do-ba-dee-doo.

Do-ba-dee-doo
