Why are we always arguing? Let's play something instead :)
I remembered an interesting forum game - Associations.
The idea is that the host (whoever wants to be) comes up with a word, phrase, or name. The task of the other players is to guess what the host came up with. As a hint, the host posts 3-4 pictures that he associates with that word.
Example (one word, a common noun):
2 Napoleon
3 Checkers
4 Bermuda flag
I don't know what they have in common :)
