Ghost Busters

I'd never seen it before so I watched it instead of sleeping. This thing is suppose to be a comedy I guess. I've laughed:
1) When Rick Moranis showed up for the first time.
2) When I saw this lady in the Bertoli ad:

3) The elevator ride in the hotel after the pack is turned on
4) Heh, 1984 CG efforts...
5) ...

Observations:
1) I had no idea Sigourney Weaver was in this movie!!
2) The Ghost Busters theme song still rocks after all these years.
3) Reginald VelJohnson, the dad from Family Matters, has been type cast as a cop.
4) Bill Murray's best movie is still Groundhog Day by far!
