Andy Roddick:
The *NSYNC loving tennis pro (with the "I love Justin" necklace) Palmer (Brooklyn Decker) meets on the plane at the end of the movie is her real life husband.
J.D. McFunnigans included the animatronic band Rock-afire Explosion from the now closed restaurant chain Showbiz Pizza Place, which was popular in the 1980s.
When Devlin claims that her husband made all his money suing the Dodgers after being hit by a foul ball. That is not legal. There is the law "Assumption of Risk" which goes into effect at baseball games. If you get hit by a ball, you are not allowed to sue because of that law. He would not have been able to sue, let alone get money from the Dodgers.
When Katherine drives into the parking spot at the pizza place, she parks correctly in between the lines but when she exits the vehicle, her car is parked diagonally across two spaces.
