By far the movie's best message is that families come in all shapes and sizes and that a parent's love is unconditional. The Chipmunks learn that just because you disappoint or disobey your parent doesn't mean they stop loving you -- but it does mean there are natural or logical consequences to your behavior. Also messages about the strength of brotherhood.
Physical comedy includes gags where characters are mildly injured -- or look like they'll be hurt but then aren't. In one scene, a fight escalates to a full-on brawl. Toothpicks are thrown at a man's face, and they sink in for a moment. On an airplane, animals are let loose, causing mass panic and a few people harassed by pets running amok. A Chipmunk slingshot hits the air marshal in the groin. The air marshal has a gun and takes the Chipmunks and Miles into custody after an emergency landing.
Some lyrics are suggestive -- like "I like big butts, and I cannot lie..." Some flirting and jokes about who's "hot." A human couple embraces/kisses.
Instead of "Thug Life," a tattoo says "Munk Life." Insult language like "loser," "squirrel," "psychopath," etc. The lyrics of "Uptown Funk" are changed to say "heck yeah" instead of "hot damn" in the chorus.
Lots of Apple gear: iPhones, MacBooks, etc. Other recognizable brands and companies include Speck tech accessories, Chuck E. Cheese, Altoids, American Airlines, Speedos, Pioneer, Beats headphones, Ford Mustang, BNW, Krispy Kreme donuts, Martinelli's cider, YouTube, Twitter, and more. American Idol plays a significant role, as the Chipettes are the judges. Off camera, the Chipmunks are featured on McDonald's Happy Meals and various toys, video games, and apparel.
Drinking, Drugs & Smoking
The Chipmunks and Miles play in a country & western bar, where adults are drinking, but the camera focuses more on people dancing. While in New Orleans, people march with beads and drinks, and the on-duty air marshal is offered two different drinks containing moonshine.
