Pap Test PSA: Video

Saw this PSA from the Michigan Department of Community Health (on BroganBlog) and thought it was a pretty clever 30 second ad. Why do I think it works:

1. Good use of humor. (Come on, you laughed a little, right?)
2. Simple, clear message. 
3. Songs just get stuck in your head.
4. Links to birthday so you don't just think about getting tested once, but once a year.

What do you think about this PSA? Was there anything missing?
