Dude you don't want to get those people angry. My uncle once spelled it with two "g"s in an email he wrote to a friend and the next day he disappeared. His body was found two weeks later buried under a giant Lego® construction site outside of Carlsbad.

Did the Lego people ever duke it out with the frozen waffle people?

OMG! I've heard it all now! From now on I'm gonna buy the generic version. How about we call them duel gender blocks, being that they have a "male" and "female" side.

my brit husband has always called them 'lego', and has chastised me in the past for adding the 's' at the end. apparently the british are more in tune to the rules of brand identity.
