Silly Question--but still a question.....

I have one that says "___ days since last Raptor attack" and a little sign with tear tabs that says "It's dangerous out there, here take one of these".

Where did you get that?

I like the idea of using an obviously humorous one, like with raptors or aliens or whatever. A realistic-looking one would not be as much fun, I think, and might cause people to go, "Huh? What?" instead of getting the joke.
