It's just a joke :) I would rarely use mean to discuss societal distributions as they can be very misleading (good example of this is when you want to see average versus median income in unequal countries). Though I think IQ is bell-shaped so mean and median coincide or are close. Thing is, I would never be brave enough to say "80% of us are stupid". People can be smart in many different ways, I know people who are not very good at numbers but are extremely good at picking up languages; isn't that an amazing ability? Funny people, good musicians, creative people... I just really don't like IQ as a metric of intelligence so to me it really falls flat when applied to the real world.
