"No childhood is complete without..."

Name something(s) from your childhood that you think all kids should have/know/see. (besides food and water.) Anything from movies, books, places, music, sports, experiences, toys, etc.

For me, classic stories and fairytales like Alice in Wonderland, Peter Pan, Willy Wonka and the Chocolate Factory, The Wizard of Oz, etc. As well as Mickey mouse. I've never seen many of the Disney movies, but the old Mickey Mouse cartoons have a very special place in my childhood.
