The movie's main message is the importance of staying close to your parents, especially when you're an adult with children of your own. The importance and benefits of inter-generational families are stressed.
A grandfather is struck in the testicles with a baseball bat and then vomits on a kid. A boy hits his bully in the eye and is then struck in response. A famous skateboarder falls on the halfpipe after a boy pees on it.
Mild suggestiveness and a couple of slow dances and kisses between Alice and Phil. There's a running joke that a married couple occasionally role plays being an English punk lover and his girlfriend. Artie and Diane hug.
Insults like "stupid," "poopyhead," "fartie," and other silly names. A fair bit of scatological humor, such as a boy peeing on a halfpipe and an adult getting hit in the testicles and then vomiting on a boy.
ESPN, the X Games, Tony Hawk, Apple products (including MacBooks and iPods), and the San Francisco Giants are all featured in the movie.
