Bert's real life wife LeeAnn Kreischer can be seen near the start of the film, as the mom at the Sweet 16 party who Bert does not get along with.
Bert Kreischer and Mark Hamill got along very well during filming. Hamill would often make Kreischer laugh out loud by saying iconic lines of his character Luke Skywalker laden with profanity.
In this movie, Bert has a jab at his best friend Tom Segura more than once. An example of this is the words "Tom is fat" spray-painted on his wall.
Even though most of the backstory which sets up the film's plot is largely based on a true story, as of the time of the film's release, neither of Bert's real life daughters have actually ever been arrested.
