Forget about St. Patrick's Day, did you know that it is Submarine Day!

Yes, today is Submarine Day (the underwater boat, not the sandwich). Perhaps Mr. Saint Patrick himself placed his holiday on the same day to overshadow its greatness?

Either way, how will celebrate this wonderful day?

Have you ever been inside a submarine? What are your fondest memories of submarines? What is your favorite submarine? Do we really all live in a yellow submarine?
