Jimmy Fallon, host of NBC’s The Tonight Show and #1 New York Times bestselling author, returns with a heartwarming book dedicated to grandfathers everywhere. At first glance, it may seem like PAPA doesn’t do anything but sit in his chair. But looks can be deceiving. From flying a plane to playing in a band, this PAPA has done so much throughout his life. His experiences are bigger than they appear, and his stories are full of imagination, humor, and love. Through all of his accomplishments, one thing remains true: there is nothing PAPA wouldn’t do for you. With warmth and gentle humor, Jimmy Fallon reminds readers that even when it doesn’t look like it, PAPAs are always doing something—and they are always there.
