Most have a favorite Dr. Seuss book. I grew up loving them and I still do. Among my favorites:
There's a Wocket in My Pocket
Hop on Pop
I Wish that I had Duck Feet
Green Eggs and Ham
Go Dog Go (see correction below)
I also get a kick out being able to caption a picture "Kirkus at Circus McGurkus"
Happy 106th Birthday, Mr. Geisel. Thank you for giving us such magnificently melodious manuscripts, Dr. Seuss.
Correction: Well then, I thought Go Dog Go was a Seuss book. It's by P.D. Eastman. He worked closely with Mr. Geisel and to this day many think they are the same author. I still love the book.
