That's odd; he makes me laugh the way Richard Nixon once did. That is, not at all. Probably an age thing, but it amazes me that two of my favorite comedians could give birth to this completely unfunny person.
I've said before, Stiller gets on my nerves. Don't know how to describe it other that he is an annoying spaz. His acting never seems natural and the comedy comes off as forced in a "Friends" type of way.
I've got admit though, it worked in this movie.
