Inside Jokes (sort of)
There were a few moments in the movie that I found particularly funny...only because this movie is 21 years old and I know these actors' futures. Of course none of these "jokes" were intentional by the filmmakers or understood by audiences at the time of its release.
1). Brendan Fraser acting like an ape and doing a Tarzan-like call. And later starred in George of the Jungle.
2). Matt Damon and Ben Affleck part of the same group of friends and even seen laughing and dancing together in the dorm "party" scene. I'm pretty certain that in 1992, the general public didn't really know who Damon and Affleck were, nor did they know that they were childhood friends.
3). (Similar to #2) Matt Damon, Ben Affleck and Cole Hauser all play friends in this movie. And of course they would later all star together in Good Will Hunting.
