The same men who were responsible for “Dumb & Dumber,” “Kingpin” and “There’s Something About Mary” are behind “Fever Pitch” – an ordinary and heartwarming romantic comedy starring Jimmy Fallon and Drew Barrymore.

Are you kidding me?

The Farrelly brothers – kings of gross gags, offbeat hilarity and big-hearted (and sometimes handicapped) heroes – have ventured into foul territory with an adaptation of Nick Hornby’s autobiographical novel of the same name – and cast the guy who ruined SNL skits by giggling and the saccharin sweetheart from countless romantic comedies.

The movie opens by introducing Ben (Fallon) as a young child attending his first Boston Red Sox game with his Uncle Carl (Lenny Clarke) – the day he fell in love with the team.

Jump to October 2003, when high-school teacher Ben meets corporate-workaholic Lindsey Meeks (Barrymore) and opposites attract.

Lindsey and Ben’s relationship fares well through the winter until March, when spring training begins and Ben’s other side appears: Baseball-season Ben – the Ben that hasn’t missed a Sox game for 11 years – stocks his closet with team jerseys and appeared on television rating a Sox game higher than sex.

Lindsey finally realizes why “perfect” Ben is still available (you would think numerous encounters with an apartment decked out in Sox paraphernalia, including a Fenway scoreboard replica in his living room, would tip her off), and Ben fears losing Lindsey just as he lost other girlfriends who were jealous of his first love.

The two compromise: While Lindsey needs extra time to work toward a promotion at work, Ben can spend his time at the games. As the season goes on, finding middle ground between Fenway Park and love becomes increasingly difficult.

While the movie isn’t bad, it’s just an average romantic comedy. It is shocking this is a Farrelly film – viewers deserve better. The closest we get to the oddball humor expected is an offer by Ben’s friend to shave an unmentionable place. The rest of the time, the humor is PG-rated.

At least Barrymore and Fallon have great chemistry together. Their puppy-dog stares and sweeter moments are surprisingly genuine as well as the reason the movie is likeable.

A fanatic obsessed with his soccer team in Hornby’s book seems tantalizing enough to adapt into American fare about baseball and the sports most serendipitous team – especially since the Farrelly’s are Boston fans. Their love of the Sox and hard work is apparent, considering the ending had to be re-worked thanks to the team’s 2004 World Series win.

But if one of the funniest moments includes Barrymore getting hit on the head with a ball – perhaps a little bit more comedy and a bit less romance would cause some “Fever Pitch” fever.
