6. Don’t be afraid to grow up.
As cool as the film made crashing weddings look, it’s an act of immaturity. Content in their playboy lifestyle, both Jeremy and John were caught off guard by the feelings the developed for Gloria and Claire respectively. John felt he and his best friend were getting too old to be acting as young children and his interaction with Claire cemented it. Conversely, Will Ferrell’s scene-stealing Chazz Reinhold was a wedding crashing “legend” who still lived with his mom waiting for her to serve him dinner between hook-ups.
