Broccoli? Really?

Yesterday, Newton expressed some interest in the broccoli I was eating. I gave him a piece in order to demonstrate that it wasn't something he really wanted. This approach had worked before, with spinach. Newton took the broccoli bit over to his Eating Spot, chewed on it, spat it out, picked it up again, and repeated until he had eaten the entire thing. Then he came back to me looking for more. I guess my demonstration failed.
