Jokes in movies that you didn't see the first time

While not a great movie (obviously), pretty funny moment that I never noticed.

When the guy throws a snake in the microwave to kill it, he hits a button on the microwave labeled "SNAKE". As in, the microwave has a built in setting for cooking snakes. Pretty funny.

Anyways, what are other jokes that you didn't notice the first time you saw a movie?

Dexters ending. It's so funny because it's so bad. It was meant to be funny, right? Phone Post 3.0
