Factual error: The truck's gas tank is said to be empty, but is able to explode spectacularly later on. An empty gas tank may spout a jet of flame, but will not have enough force to rupture and damage the truck, a full tank of liquid gas will not burn unless vaporized. Simply put the truck would not explode in that Michael Bay fashion.
Factual error: The film tells the stories of five male/female couples. They have conflicting aims in their relationships. For example, one wants to become a parent while the other does not want children. Thus they all obtain supplies of contraceptive pills (in bottles) and re-label them as aspirins or vitamin tablets (or vice versa) depending on whether they want pregnancy or not. The bottles get mixed up, causing panic and anxiety for all involved. All the interlocked stories are based on a complete error. Contraceptive pills are not stored in bottles. Contraceptive pills are packaged in 'blister packs'. This basic fact makes a nonsense of the entire film.
