Click was hilarious how it was randomly SUPER SERIOUS AND SAD at one point, they did it in Funny People too, but FAILED HARD. That movie was so bad.
I liked Little Nicky a lot, if just for a funny take on the occult.
Classics, like kinjo said, Billy Maddison, Happy Gilmore, Waterboy.
Mr. Deeds was the start to the downhill slope of the Happy Maddison movies.
