Vince Vaughn plays the biological father to 533 children in his latest movie, Delivery Man. And while the plot doesn’t dictate that a great deal of intercourse led to this ridiculous figure, MTV have investigated, and even the sperm bank story doesn’t add up for this absurd premise.

"Considering the probability of pregnancy using frozen sperm — 20 to 30 percent and the probability of successful pregnancy with a live birth v10 percent — it would take a minimum of 1,250 vials of sperm to 'make' 500 children," said Dr. Grace Centola, the past president of the Society for Male Reproduction and Urology of the American Society for Reproductive Medicine.

"If a normal ejaculate results in about four vials, this would mean that the man would have had to donate about 300 ejaculates. No sperm bank would allow a donor to donate that many specimens over a several year period of time."

But just because the film’s plotline couldn’t necessarily happen in real life, that doesn’t mean the movie as a whole is rubbish. Unfortunately for Vaughn, a host of other factors have indeed rendered it rubbish, culminating in a lousy 38% rating on Rotten Tomatoes.

“The concept's execution is sloppy, full of inconsistencies and plot holes. The situations teeter on funny, but never achieve it. And sections meant to be heartwarming feel lukewarm, far-fetched or inappropriately comical,” said USA Today’s Claudia Puig.

Peter Hartlaub of the San Francisco Chronicle was equally unimpressed, writing: “‘Delivery Man’ is nowhere near the worst film of 2013, but it is definitely the most exhausting.” Laremy Legel wittily jabbed: “The moral here is that you should never try to learn the identity of your biological father because he might be Vince Vaughn,” in his review for Film.com.
