Dumb and Dumber (1994)

Continuity mistake: When Lloyd tackles Mary on the hotel stairs, she is wearing black pantyhose. By the time they get to the hotel room, she has miraculously changed into grey tights. (01:28:45)

Harry: I expected the Rocky Mountains to be a little rockier than this.
Lloyd: I was thinking the same thing. That John Denver's full of shit, man.

Trivia: In the bar scene Lloyd sees the newspaper clipping on the wall and says "No way! We landed on the moon?" This wasn't in the script - Jim Carrey improvised the line and it was left in the movie.

Question: What is the trailer both were watching on TV while they were having some snacks in bed in the Aspen hotel room?
