A brawl in a bowling alley is depicted, with various injuries and substantial damage.
After being casually insulted by his new employer, one character vandalizes the business's time clock and quits.
The main character is deliberately injured by a group of cyclists who find his attitude irritating. The injury is not serious, but causes him some pain for a while.
Several characters chase a man who they mistakenly believe has been flirting with the girlfriend of one of them. The end of the chase is not depicted, and it is unclear whether they catch or harm him.
Someone's mother makes a questionable joke about possibly strangling her adult child while he's asleep (see the trailer).The main character crashes on his bike and blood is shown. It's not too gory, but again, it may frighten some younger or squeamish viewers. Blood is shown running down a leg (not dripping, but still there).
