CHICAGO (AP) — Former President Barack Obama and former First Lady Michelle Obama surprised the first 100 visitors to walk through the doors of the new Obama Presidential Center, personally greeting them Friday.

The Obamas, joined by former host LeVar Burton, also read “Where the Wild Things Are" to 25 school children at the Chicago Public Library branch inside the center. When the former president read Maurice Sendak's line about being “king of all the wild things,” Michelle Obama interjected with, “Although there were no kings,” to applause.
