Pi ARRR Squared

Tina M. send in today's first plate, snapped by her husband, Ray. I had to stare at this one for a while, I cannot lie. It says "pirate." How you ask? 3.14 is a shortened version of the number "pi." Put it all together and you get PI-R-Eight... Pirate. A smart pirate, at that. Yarrr!
So many pirates driving cars, so little time, I tell you. Heidi sent us BK BERDS (Blackbeard's). In case you don't know, Blackbeard was a notorious English pirate. Was he also known for his notorious English? I could have used a few more consonants in that plate.
AVASTYE (either the worst spelling ever of AVAST or AVAST YE) is from Jenna Lee A. According to wisegeek, avast means:

... to stop or desist... Avast should be used to attract attention, much in the way that someone shouts “stop” to a driver who is at risk of colliding with something.

Exactly.
