Today is Mario Day, apparently. March 10, Mar10 - geddit! After cracking its collective knuckles and preparing to amuse us all, Nintendo is promoting today as Mario Day across its social networks. It is an excuse for fans to tweet nice things about the famous mascot, however, so that's fine by us.

If you're in North America, this day also brings an online sweepstakes to win a copy of Mario Party 10.

That aside, some tweets using the #MarioDay hashtag are quirky...

Feature freaky mascots...

Weird corporate messages...

And finally rubbish and dull corporate messages...

Happy Mario Day everyone, and stay tuned for our feature today on the Metroid series! Wait, that can't be right...
