Is Lex Luthor Addicted to Superman Peanut Butter?

In 1983, Sunnyland Refining Company began producing jars of creamy and crunchy Superman peanut butter.  As you can see in this commercial for the product, apparently Lex Luthor loved the peanut butter more than anyone else.  

Really Lex?  All the varieties of peanut butter in the world, and you got hooked on your archnemeisis' peanut butter?  I mean he's got one huge hunk of kryptonite in this commercial, and his grand plan is to use it to find out the secret recipe of Superman peanut butter.  Hey Lex, you're a billionaire, just go buy yourself several cases of it. 

C'mon Lex.  You're better than this.
