Here are the rules:
1. The person who posts the topic (me), posts a picture of something (for example, a cannon).
2. The next poster posts something that "beats" that (for example, a grenade).
3. If you can't come up with a better thing, you pass. You can't double post, and you must wait for at least 2 other people to "fight" before you post again.
Let me start:
Beat that!
Good luck all.
