As long as you are not easily offended (and if you are, you are likely missing out on a ton of great comedy), this movie will definitely tickle your funny bone. It's like a super-amateur production of a Judd Apatow type movie. The best part is, the miniscule budget very rarely hurts the movie because the script is filled with hilarious interplay and dialog, so even shoddy acting, lighting and cinematography can't bring it down! It's not just "good for it's budget," it's just good. It's squarely aimed at guys in their mid twenties, and it makes the most of its one-joke premise by not making the faux-retardation scheme the actual focal point of the movie. Rather, the main character's relatable group of friends, combined with awkward interplay between male and female, and a playful, almost surreal tone, is where the movie really succeeds. While it is most definitely a stupid movie with a stupid title, "The Truth About Average Guys" is an absolute treat and if it had bigger names and a bigger budget, it would have been a hit that could sit comfortably in cineplexes alongside such movies as "Knocked Up" and "The 40 Year Old Virgin."
