When I am the judge, I usually pick the weirdest or most disgusting combination, as I find these to be the most funny. In the above case, it would be a tough choice between 'juicy- pigeons' and 'juicy- having an operation'. My friend, however, always goes for the most literal card, 'juicy- oranges'. I also like hearing the judge's reason for their choice, as it is often accompanied with some sort of back story.
About 80% of the time, I inadvertently pick my husband's card, as he knows my strange, twisted thought processes better than anyone else in the room. In contrast, when we play 'codewords' on the same team, we almost always lose... interesting.
Which one would you pick?
