I watched Coneheads a few weeks ago to see if it still held up. It was still hilarious to me and apparently there was some mature stuff in it I didn't pick up on when I was a kid. I think it was Dan Akroyd's funniest role other than Ghostbusters, The Blues Brothers, and Spies Like Us. So..it's probably in the upper half of Akroyd's comedies.
If you can't enjoy a cheesy comedy, you can't like any comedy from the 80's or 90's.
