If I may add some less well known (but still fun) cooperative games.

Insider (Oink Games) - 20 questions with a twist. The twist being that one player knows the secret word and wants people to guess it, without being found out.

Hey Yo (also Oink Games) - small and cute rhythm game where we try to place cards on the beat, scoring points for uninterrupted lines of the same color cards.

Rail Pass (Mercury Games) - play this with people who are turned off by overtly competitive train enthusiasts. You try to hand over trains filled with cargo without dropping it and getting the right cargo to the right player. But you have to make train sounds before handing it over to them. Great fun. Especially with adults.

Romeo & Juliet (Sylex) - a challenging two-player game of unspoken communication, where you try to get Romeo & Julia to fall in love with each other while still making it to the end alive.

Kreus (CMON) - similar to the above, but for up to 4 players. Create a planet by playing cards in the right order using only logical deduction and sparse information. A brainteaser that feels amazing when you pull it off, but need to pay close attention and think two turns ahead to do so.

Space Cadets (Stronghold Games) - an underrated Star Trek style game of wild, real-time cooperation. Players each have individual roles (and rules) to fulfill at their station. Only if everyone pulls their weight do you stand a chance. It's not a very elegant design, but once you make it past the learning curve it's a fantastic experience.
