(While the drinking game is traditionally a game with alcohol if alcohol is not  your preference you can substitute other drinks, eating chocolate, anything of your choice really)

Here's all the suggestions from the first chat session including the last two rows from Jose Molina via Twitter.

And from the following day when Jose popped into chat

• When she calls Castle kitten.
• i think "castle/beckett steal an unseen "wanting look" to one or the other warrants a drink.
• Castle puts his foot in his mouth – 2 drinks at least.
• castle wears his writer vest – 2
• i think espo saying "yo" is 1!
• 4 shots when beckett unbuttons or unzips her coat/jacket indoors
• beckett draws her weapon – 2
• someone calls castle "rick" or "ricky" – that's 2
• someone calls beckett "kate" – that's 2
• castle makes a pop cult reference – 2
• but castle tosses out pop cult references like crazy — cape fear, strangers on a train, etc.
• when esposito uses a handgun instead of an assault rifle
• castle disobeys beckett – 2
• beckett in a dress/ castle in a suit – 2

After going through everyone's responses I've chosen the most popular points.  I then gave them either 1 drink, 2 drinks or 3 drinks based on how frequently they occur.

Not everybody can (or wants to) drink alcohol so this game can be played with substitutes, for example, instead of 1 alcoholic drink, substitute a non alcoholic drink, a piece of chocolate, a spoonful of icecream, whatever you like, so long as it's fun!

We'll test this out in the chat room during tonight's episode "Famous Last Words" so come prepared! [Link to Chat]
