According to the company LEGO turns 50 today because it marks the anniversary of the patent approval for their famous interlocking bricks. HAPPY 50th BIRTHDAY LEGO! This is also the 30th year minifigs have been in existence. So HAPPY 30th YEAR IN EXISTENCE MINIFIGS! I love you all so much. Please enjoy the cake I made for you. Maybe afterwards we'll head down to the bar and I'll drop a couple of you in my beer. Feel free to drink as much as you want, just don't choke me if I accidentally swallow you.
