The best thing is to watch the movie with a man who was a kid in the late 1940s - so much of what's in that movie has them laughing in recognition and nostalgia.

But as a female who grew up in the late 1960s, I find it really funny too. Yes, some things make me cringe (don't touch the flag pole!), but I still laugh too.
