Where did you come from?!

Wait, where'd that guy come from?!

I chose the assignment for my third ds106 work.
The description says...

Photoshop someone(s) (or something(s)) into a picture that isn't supposed to be there.

OK. Here is "someone".

Me at school. And here's something.

Then result!

Find me :)
I used Adobe I used Adobe Photoshop Elements 7.0.
