Unfinished Sentence

I guess last week I meant to use a different tense in the sentence. I was thinking along the lines of "The best candy filling would be ______", as in "The best candy filling would be lephrecauns".

So I'm going to declare the winner of this week me, with the above sentence (it's my game, I make up the rules).

This week's sentence:

"If only Scott Baio had gotten the part of ______ the world would be a better place."
