Here's how to play this game: One person will start a sentence and the next person would change up to three words in that sentence and repost it. The third person will take the second person's version of the sentence, change up to three words in it and then post again. And so on and so forth!

RULES:
1. Changes can be replacing a few words, adding a few words, or deleting a few words.
2. They should not be big changes and the sentence should still make grammatical sense, but other than that, the resulting sentence can be as random as you want.
3. After you post, double-check the post before you to make sure that the previous post was the one you meant to respond to.
4. General forum rules apply.

EXAMPLE:
Person 1: "A bank robber gave my chiropractor a bone."
Person 2: "A bank robber gave my chiropractor a walrus bone."
Person 3: "A bank gave my chiropractor a walrus bone."
Person 4: "A bank gave C.S. Lewis's chiropractor a walrus bone."
Person 5: "A bank gave C.S. Lewis's acupuncturist a walrus bone."
etc.

So, to start us off:
