It's great to have a good arsenal of funny movies for kids and adults if you have kids or when you're caring for other people's kids. A certain percentage of funny movies have been scientifically proven to keep both adults and kids laughing throughout the movie's duration. Here are just a few of those. 

  1. "Scooby Doo on Zombie Island" Remember watching those meddling stoner kids solve mysteries on their way to rock music concerts? This funny movie from 1998 follows Scooby, Shaggy and the gang into their adult years. Scooby and Shaggy hold down jobs as airport customs agents, Daphne is a talking head news anchor and Fred is her producer and camera man. The team meets up again in New Orleans for the first time in years after burning out on mysteries. Then a little girl invites them to a haunted house where a pirate named Morgan Moonscar died. Kids and adults have been shown to laugh out loud in clinical trials during this funny movie. 

  2. "The Looney Looney Looney Bugs Bunny Movie" This hilariously funny movie from 1981 weaves together many classic "Looney Tunes" episodes into one. In part one, hell bound Yosemite Sam makes a pact with Satan to escape hell by replacing himself with Bugs Bunny. Sam tries to get Bugs Bunny to sin before killing him, but it never works out. Mafia gangster Rocky kidnaps Tweety in the second segment, and the local cops deputize Bugs Bunny to apprehend him. Part three focuses on the "Oswald Awards" ceremony, which is a parody of the Oscars. It goes without saying that this is a ridiculously funny movie for kids and adults. 

  3. "Abbott and Costello Meet Frankenstein" Where can you find Abbott, Costello, the Frankenstein Monster, Count Dracula, a wolf man, a female mad scientist and the Invisible Man all in one place? You'll find them all in this 1948 classic movie that kids and adults will thoroughly enjoy. Yugoslav actress Lenore Aubert stars as a mad scientist who needs a very simple brain to revive Frankenstein's monster after a considerable downtime. Lou Costello's brain becomes the number one candidate for the experiment. Lou does not realize the plot until a wolf man tells him what Count Dracula and the sinister mad scientist are up to. Vincent Price makes an invisible and brief appearance as the voice of The Invisible Man who shows up just to check out the scene. 

  4. "Ghost Busters" "Saturday Night Live" stars Dan Akroyd and Bill Murray team up with Ernie Hudson, Rick Moranis, Sigourney Weaver and Harold Ramis in this funny movie from 1984. A paranormal investigation team cleans up New York City of ghosts and other supernatural undesirables. Moranis and Weaver channel an ancient Babylonian spirit that ravishes Manhattan, and the "Ghost Busters" save the day. Kids and adults alike will enjoy the big showdown with the Stay Puft Marshmallow Man in this movie that has been proven to be funny time and time again in laboratory settings. 

  5. "Home Alone" This 1990 movie is so funny for both kids and adults that the makers produced two sequels. Macaulay Culkin plays Kevin, a kid who hates his very large family and wishes that they would go away. He gets his wish when the family's headcount on route to France for a Christmas vacation goes horribly wrong. Kevin has a lot of adventures at his suburban Chicago home, where two slapstick burglars, played by Joe Pesci and Daniel Stern, try to break in. Kevin is a smart cookie who foils them both. Scientists agree that "Home Alone" is a classic that is best known as a funny movie for both kids and adults. It's an obvious choice that will suit your needs for laughter quite well.
