As a teen in the 90s I remember this movie very fondly when it came out. It was a ground breaking comedy at the time. This kind of humor has become the norm and been built upon so it doesn't seem as special now but it was really something when it came out.
Stiller is great as the all too familiar tough luck nice guy and Diaz is adorable.
The ensemble cast sing-a-long to "Build me up buttercup" at the end was great. The Farrelly brothers never topped this one, in my opinion, as within the silliness and gross out humor the tortured lost love theme rang true to lots of people.

This film is one of those comedies that never looses its appeal over time for me. The real stand out star of this film is Matt Dillon whose comedic performance so beautifully nuanced in every detail he steals every scene he's in effortlessly with his smarmy, awkward and charmingly inept character Pat Healy. Honourable mentions to Lee Evans, Lin Shaye and Jeffrey Tambor also.

My favourite Farrelly flick.

Eh. Asides from the main parts everyone remembers, it's not as funny as you think.
