The Waterboy is a 1998 American comedy film directed by Frank Coraci. It stars Adam Sandler alongside Henry Winkler, Kathy Bates, Jerry Reed, and Fairuza Balk. Lynn Swann, Lawrence Taylor, Jimmy Johnson, Bill Cowher, Paul Wight, and Rob Schneider have cameos. Sandler produced the movie and co-wrote the script with Tim Herlihy.

The movie was extremely profitable, earning over one hundred and eleven million dollars in the United States alone and made Sandler a successful actor with The Waterboy becoming his second $100 million film in a year, along with The Wedding Singer.

Sandler's character, Bobby Boucher (pronounced "Boo-SHAY"), bears a strong resemblance to his "The Excited Southerner" comedic skits from his album "What the Hell Happened to Me?" The portrayal is one of a stereotypical Cajun from the bayous of South Louisiana, not the typical stereotype of a Southerner. He also shares similarities in speech and mannerism to Canteen Boy, a recurring character, also portrayed by Adam Sandler, on Saturday Night Live. Like Bobby, Canteen Boy preferred "purified water, right out of the old canteen", which he always carried with him.
