Well the first one was kinda platform and silent in most of the period but still during the cutscenes they were some funny moments. The Second and third one continued the laughs a bit more in my opinion. I didn't play a lot of funny games to be honest preferring serious stories or shooters (except most of the Square Enix games but they're not funny).
The Jak and Daxter trilogy was the only game saga that made me laugh at some points and I seriously enjoyed it a lot so Jak and Daxter for the win :P.
