Seth Meyers started his "Corrections" segment on a whim

Vanity Fair

"The segment," says Joanna Robinson, "has transformed from a 2–3 minute bit into an irreverent, hilarious feedback loop between Meyers and his online audience which has grown in both viewership and length as the running gags and inside jokes pile up. You may have to start at the very beginning to get every reference, but Meyers’s evident joy during 'Corrections' is contagious enough for even the most casual viewer." Meyers adds: "It started because I never received more Twitter messages than when I said 'Lego block' instead of 'Lego brick.' Then I basically just said to Shoemaker one afternoon, 'Hey, at the end of the show on Thursday, I want to do this and we’ll just put it up online.' Then it just kind of grew from there. We film it after we finish taping on Thursday. So it’s the last thing we do (before the weekend)."
