Got an Idea for a Rubber Stamp?

You need a stamp? Well do you....punk? Make my day.

Seriously though, I hand carve custom stamps, but I'm always looking for input for rubber stamp ideas. I got started in carving rubber stamps because I needed a stamp of a bear track, and couldn't find one for sale. So I'm hoping there is an idea for a stamp that you have had, but can't find at the craft or stamp store.

So here is my CHALLENGE to you!
1) Post in the comments of this post an idea you have that would make a good rubber stamp and why.
2) Please make sure the idea is a generic one, like "spaceships", not "an X-Wing Fighter" (since that would be a violation of copyright.)

[Please note, the Clint Eastwood stamp pictured was never a stamp for sale, it was only used for my personal use! I don't sell copyrighted work!]

If I like your idea, I'll probably carve it!

Let's hear you idea!
