Don't play the fool!

Watch out! Pranks and pratfalls are most likely headed your way today! I thought I'd put out these cheerful little messages in honor of April 1st...found on my new favorite e-card site, someecards.com...

I couldn't decide which one I liked better...

I honestly forgot to play any jokes this morning--didn't remember the date! And I'm off to a board meeting, where they might (?) stage something silly but who knows.
I'd love to hear about anyone's particularly good April Fools jokes--past or present year....spill it!
