I think that Red's birthday might not be set in his control panel so it's not showing up and Nelson has no way of knowing either since he's usually in charge of starting the birthday threads.

But I and a few others know it's the big man's birthday today so I'm taking this opportunity to wish 'Red' all the best he can wish for in life (especially those super large heavy blades) and hope you enjoy this day!

HAPPY BIRTHDAY RED
