"I think a lot about how I felt when I was a kid... I was six foot, four inches since I was 12. Kids used to stand around me in a circle and one by one they would jump on my back and then the rest would chant, 'Ride the oaf, ride the oaf...' I had a lot of really uncomfortable feelings when I was a kid and I think that by talking about that and writing about that, it means they don't have to be lonely feelings... I talk to kids about their fears and it turns out a lot of kids are afraid of being made fun of by their friends." Actor and writer Jason Segel loves to share his childhood fears in his Nightmares! books.
