I've heard of Dijon mustard, but never in my life had I heard of Dijon ketchup.
LOL I think it's time to quote the actual bit in question. There's this in the actual song:
If I had a million dollars
We wouldn't have to walk to the store
If I had a million dollars
We'd take a limousine 'cause it costs more
If I had a million dollars
We wouldn't have to eat Kraft dinner
The Kraft dinner being the mac and cheese, I think. Then there's a bit of chatter following it:
But we would eat Kraft dinner?
Of course we would, we'd just eat more
And buy really expensive ketchups with it
That's right, all the fanciest
Ket-- Dijon ketchup
Mmmm (mmmm)
