There's no reason to change that one in particular- they never mentioned Johnathan Taylor Thomas or Home Improvement. It was the already-generic Jeremy Jason McCole. Honestly, he could still stand in for any girl teen fantasy of today. Like... Justin Bieber. Girls like him, right? The things that might need to change are the references to Ahnold, for example, or Scully and Mulder- how many teens of today are going to have even heard of the X-Files?
