I have seen this on other boards and it has always been one of my favorite text games to play. This is how it works: Someone posts a word and then the next person posts a word that has NOTHING to do with the previous word posted.

Ex: (each word would be a different post and the words wouldn't be numbered)
Word1 = bubble gum
Word2 = candle
Word3 = computer screen
Word4 = carpet

I'll start: Purple
