"...I'm strong to the finish,
'cause I eats me spinach..."

When I was a wee lad, my mother used to encourage me to eat my spinach -- which usually came out of a can, horribly wilted, slippery and doused with some awful vinegar -- so that I would grow up to be big and strong like Popeye. It took many years to overcome the revulsion produced by this childhood experience. I can now eat the stuff raw or very lightly cooked, but still not the vomit-inducing stuff which comes in the tin.
