The first Flash game I stumbled across was Samorost, one of the most popular games of the genre. The game was developed by Jakub Dvorsky as a thesis for school. He got a "B" on his thesis, which proves that pointy-headed academics never have the final word.
If you want to kiss a few hours of your life good-bye, you can find it and some other flash games here. And yes, clicking on the hookah does do something. Is it sad it was the first thing I clicked on in that screen?
