Very simple:

One player types a sentence. (That one player is me). The next player changes only one word in the sentence. Easy.

Rules:

The sentence has to make sense, in the grammatical sense. So, for example, an adjective could not be replaced with a noun.
No cuss words, please. That's self explanatory,
Do not ADD words. You must CHANGE ONE word.

Okay, let's hope you have a better I.Q. than a dirty gym sock and understand this.
