Happy birthday, Stacy!
I think Calvin and Hobbes has to be my all-time favourite comic, even ahead of Dilbert (which is very funny as is). It’s a tale of a boy and a tiger, and they share a bond closer than any two humans would ever do. Calvin amuses me with his precocious cynicism and his fascination with the sub-ordinary, but he manages to warm my heart how he learns something new in his life each day, guided daily by the tiger who has a weakness for tuna sandwiches and inane fun, yet who manages to see the finer points of life that humans always miss.
Also, it would be really cool to remain six your whole life.
