I think the important thing is to READ them, though.
My kids still quote scads of dialogue from the book (after 50 years, I have all seven almost committed to memory). We were skiing on a BSA Venture Crew trip when my daughter came hauling down the slope, skis parallel, screaming, "Beware! Beware! Beware! The Bolt of Tash falls from above!" Of course she wiped out, and I skied over to the snow-covered heap and inquired, "Does it ever get caught on a hook half way?"
My family does that with Puke & Snot, Calvin and Hobbes, James Herriot, and Dorothy Sayers...
Cheers!
