Prove that you love me, lord, and buy the next round

I was, as usual, ipoding when I came across a song which I have almost forgotten. It's a hilarious, silly and short one, not exactly social satire - Janis Joplin's "Mercedes Benz". Here's the lyrics:

Oh lord, won’t you buy me a mercedes benz?
My friends all drive porsches, I must make amends.
Worked hard all my lifetime, no help from my friends,
So lord, won’t you buy me a mercedes benz?

Oh lord, won’t you buy me a color tv?
Dialing for dollars is trying to find me.
I wait for delivery each day until three,
So oh lord, won’t you buy me a color tv?

Oh lord, won’t you buy me a night on the town?
I’m counting on you, lord, please don’t let me down.
Prove that you love me and buy the next round,
Oh lord, won’t you buy me a night on the town?

Everybody!
Oh lord, won’t you buy me a mercedes benz?
My friends all drive porsches, I must make amends,
Worked hard all my lifetime, no help from my friends,
So oh lord, won’t you buy me a mercedes benz?

That’s it!
