You put a frog to sleep by rubbing its belly??!! Does that work on people too? Probably much safer than anesthetic!
We also dissected frogs in biology. But they were most definitely dead. Also, most conveniently, I remember they had had red and blue rubber injected into them so that the arteries were red and the veins were blue (hmm, I wonder, did the do that when they were still alive?)
