I'd be a serial killer...

Very clean design. Good colors, not many stamps are all green, but it draws your attention. I personally think the delay time is perfect for the amount of text, but I read very fast. Maybe a half or a quarter second more. Straight to the point at getting the message across and very specific which is what you don't see a lot of. I would drop the 'the' in the stamp because it's not proper grammar, though. Although I'm sure other people like it, hell, I didn't even notice it at first!
Keep up the good work!
