I wasn't expecting anything with this movie....
But I came to realize that no matter how many times I witness it, seeing someone get plonked in the head with a ball never ceases to be hilarious. It amazes me that it took so long for someone to come up with the idea of making an entire movie out of it.
The Lance Armstrong cameo is one of the greatest of all time. I haven't laughed so hard since the David Letterman cameo in Cabin Boy. However, that Letterman Cameo was Cabin Boy's only saving grace. The Armstrong cameo in Dodgeball was icing on the cake.
I give it a 8.5 on my ten scale, but it gets a 9.5 in the humor department.
