The Mr. Men and Little Miss books are a defining part of my childhood. Mr. Tickle used to wake me up with his "very, very, very long arms" in the morning (my Dad would read the book and if I didn't get up I would get tickled - torture!) and I loved all of the characters and the simple and funny illustrations. Google informs me that today is the creator's, Roger Hargreaves, birthday and Google is featuring his images as part of their banner today.
The story goes that Mr. Hargreaves started creating his characters and their stories when his son asked him what a tickle looked like. In his lifetime, he wrote 79 books about characters including Mr. Neat, Mr. Mischief and Mr. Jelly. If you haven't read any of these books before, definitely check them out.
