11 Things We Can't Believe About 1990

1 "U Can't Touch This."

Mc Hammer revived both Rick James and harem pants with this hip-hop hit. James sued and settled over the "Super Freak" sample; nothing could be done about the pants.

2 We knew K.D. Lang when.

The not-yet-mainstream singer's bold mix of musical styles was celebrated on the first cover of 'EW' (and later that week, she won her first Grammy, for 'Absolute Torch and Twang').

3 The NC-17 movie rating was created.

You're welcome, 'Henry & June' and 'Showgirls.'

4 "The Wall" live in Berlin.

Pink Floyd's Roger Waters and friends performed this rock opera where the Berlin Wall had stood eight months earlier.

5 Andrew Dice Clay on 'Saturday Night Live.'

'SNL' used a time delay when the shock comic hosted; Nora Dunn and invited musical guest Sinéad O'Connor boycotted this episode.

6 Roseanne Barr desecrated the national anthem.

There were some notes only dogs heard during her performance at a San Diego Padres game.

7 Milli Vanilli, Best New... Lip-Synchers?

Nine months after the duo won the Best New Artist Grammy, it was revealed they didn't actually sing.

8 Macaulay Culkin was 'Home Alone.'

"Mack is not like a 9-year-old," costar Joe Pesci told EW of the kid who carried the comedy to a $476 million worldwide gross. "It's like working with a 30-year-old midget."

9 'Law &Order' settled in for a 20-year run.

And that iconic "chung-chung" sound? It's a piece of music, composer Mike Post has said, that brings in royalties.

10 'Blue Steel.'

The Jamie Lee Curtis thriller was the cover of EW's issue 5. Regrets, we've had a few...

11 'Jurassic Park' made its mark in fiction.

"If you're going to do a dinosaur book, people must be munched," author Michael Crichton told EW, but "the ideas... are much more important to me than the munches."
