Lard

So I was driving down the freeway
on my way home from work,
flipping through channels and I hear,
"Once you fry your egg with lard,
you'll never use butter again."
And I'm thinking, "That can't be
right. How can they say that?"
Since eggs are the only think I
ever cook, I was interested, but I
just kept switching channels, never
coming back to that one again.
