The funniest foreign joke movie in the world.

I have seen it, too. It's really funny. It should be the comedy film "Dumb Agua" starring Jim Carrey, which was released on 1994. It tells a joke between Roy Chrisma played by Jim Carrey and Harry Dunn played by Jeff Daniels.

Roy Chrisma (Jim Carrey) and his good friend Harry Dunn (Jeff Daniels) are stupid partners. Not only do they have low IQ, but they can't find jobs. Once, Roy got a temporary job to drive modern girl Mary swanson (Ron Holly) to the airport. Roy fell in love with Mary at first sight, but they were very different. When Mary boarded the plane, Roy found that Mary had left a suitcase in the waiting room. So, in pursuit of true love, Roy decided to drive with Harry to the plane destination mentioned by Mary. He will not only return the suitcase, but also pursue Mary. However, it seems that the suitcase is not that simple. This suitcase was a ransom paid by Mary to the kidnapper. The kidnappers tried to kill Roy and others, but Roy's IQ was unusual and he escaped the disaster by mistake. Two idiots, can you reach your destination. Began a silly and happy journey.

You can also watch the movie "When A Dai Meets Agua" in 2003, which is the prequel of Dumb and Agua, and tells the story that their high school time was suddenly pulled back to 1986.
