Azizi asked:

Does anybody remember the last line to this Post Sugar Crisp cereal commercial:

Can't get enough of those Sugar Crisps
Sugar Crisps
Sugar Crisps
Can't get enough of those Sugar Crisps
????

I remember it as

Can't get enough of that Sugar Crisp
Sugar Crisp, Sugar Crisp
Can't get enough of that Sugar Crisp
keeps me goin' strong!

or possibly "It keeps me goin' strong!" It was sung to the tune of "Joshua fit the battle of Jericho".
