The description says it all in saying that the title says it all; what's the craziest or coolest thing you guys have ever Photoshopped?

I haven't done much with Photoshop outside of spriting for my webcomic, but one time for Computer Graphic Art class, I had to swap the heads or Laurel and Hardy. That was the perfect time to use the line "We're not us, we're two other fellows!"

But, as usual, my older brother has me beat in this category. Being a newbie, I can't post the actual picture (also, I can't find it), but I can describe it. He started off with the famous painting of Napoleon Bonaparte on his horse, and went from there. He made the horse black, darkened the background, and turned Napoleon's cape red instead of yellow. But where the REAL fun begins is in the next things he did. He made it so that the horse was breathing fire, and gave Napoleon a mustache, a red lightsaber, and a Jamba Juice cup! The picture was so awesome, his history teacher hung it up in his classroom, and it's still there now that I'm in that teacher's class.

So do any of you think you can top that for awesomeness? I eagerly await your responses (if any).
