Lyrics - what song, what singer?

There's this song.

A guy with a really deep voice.. like..errmmmm Barry White or simillar, right? And he's singing about himself getting into trouble:
"Trouble.... Big, big trouble (oh no!)". And then he is singing about taking the boss's wife in the elevator at work. Then about him driving downtown and feeling so beautiful, he decided to take all his clothes off.....

I love this song but for the life of me, cannot remember who sings it or even the name of the song....

Oh, the Simpson's people took this song and changed it slightly so Bart is singing it.... rings a bell?

Thanks for looking!
