Corrected entry: Adam Sandler is visiting Susan Sarandon in prison. Whilst tapping the glass with his finger the boom microphone makes a brief cameo appearance at the top of the screen.
Corrected entry: Adam Sandler plays Andy Samberg's father in the movie, even though in real life he's only 12 years older than Samberg.
Correction: This can hardly count as trivia since the point of the movie was Donny (Adam Sandler) was just 13 years old when he impregnated the mom.
Correction: The boom microphone isn't part of the movie crew, it's part of the camera crew for the TV show that Adam Sandler was supposed to have them on for the reunion. They notice the microphone and that's how they realize the show is being filmed. Not a mistake, a plot device.
