Thankfully, I did NOT still have every line memorized after all these years. (I sat there not-turning-it-on for multiple hours in fear that I would still remember it all and would have to plunge a leatherman into my gut in shame.)
But it was still kind of embarrassing to realize how much I *did* still have memorized.
Also, it turns out that I had in fact never seen the 3rd film, which is way better than the second. Of course, all you had to do to achieve that was drop the cartoonish one-off new mutants...and VANILLA ICE. *headdesk*
