He's been eating for 40 years and he's still hungry

Happy birthday to the Very Hungry Caterpillar by Eric Carle. One of the best children’s books ever.

No doubt you'll pop into the shops and be overwhelmed with 40th anniversary special editions and products such as pop up books and DVDs.

But nothing beats the beauty of the original simple story about a little green grub who ate what he wanted without his mummy having to worry about obesity.

Ahh, the good old days. Celebrate them with a DVD, no doubt they will be available everywhere.
