I can't believe it's not butterfly

Thinking specially of you, dear Shadow dweller, here's one from the vault:

If I were a butterfly,
I'd thank you Lord for giving me wings.
But I am a lite, polyunsaturated 98% fat free margarine-fly
And when people see me they just cry:

"I can't believe it's not butterfly,
I can't believe it's not butterfly,
I can't believe it's not butterfly,
I can't believe it's not butterfly!"

Just imagine what would happen if that one spread.
