What is the Lyric Interpretation of This Dead Milkmen Song?

Question

If You Love Someone, Set Them On Fire

"You know that it would be untrue
You know that I would be a liar
If I were to say to you
I didn't set your house on fire
But it's just the way I am
You'll have to take it for a fact
Life can really burn you up
When you're a pyromaniac

If you love somebody
Better set them on fire

I went to your house last night
Your dad called me the human torch
Got a little pissed at him
so I burned down your front porch
Now I feel a little bad
About pouring gas on your dad
But you know it's hard to quit
And besides he started it

CHORUS

I just bought a brand new lighter
And I cannot wait to use it
Oily rags are special things
You know to me they're diamond rings
Maybe we can have some fun
Maybe we can burn someone."

Answer 1

Knowing the Dead Milkmen's style of music and songwriting, I'd say it was just a lark. They never took themselves too seriously, so their songs are mostly silly. It's funny though, that they mention The Doors a bit. In this one, they borrow heavily from "Light my Fire."

Mainly, I just think it was their way of having some fun while writing a breakup song. They took the old cliche "If love someone set them free" to a new level.
