Sometimes you may miss an obvious joke just because it’s that obvious. For example, in Spider-Man 2 (2004), there’s a scene where Peter Parker states that he needs to have “strong focus” on what he wants before jumping off a building. He takes a leap, screaming, “I’m back” before falling down, landing on a car, and rolling off.
If you look closely, you will notice that the car is a Ford Focus, and the fact that it didn’t even get a scratch after he fell on it proves that it is indeed a very strong Focus. Ha!
