This game requires at least one other person (easiest with just 2 total, but more makes it crazy....but fun)
1. Each person says a random word at the same time
2. The players take a few seconds to think about what the common thread is between the two words
3. When both players are ready, they say the word that they think is the common thread
4. Continue until both players say the same word.
For example:
Player one says: Apple
Player two says: Paperclip
Both players take a second to think of a single word that has to do with both of the above words and shouts it at the same time (for example, someone might say 'teacher' as a word that ties the two previous words together since they're both on a teacher's desk.)
Continue as above until both people say the same word.
