You are both wrong. The boyfriend was Craig. His friend with the funny pronunciation was Ian or "Een".

This may show my age (though really I am only 42) but I am so excited to see Marty featured here.  It has long been one of my favorite movies.  Ernest Borgnine just makes you root for him in such a natural way.  My mom still watches this movie at least once a month.  It really is such a sweet little movie.

Not Joey Lawrence.  It's Matthew Lawrence.
