Does the name "Pavlov" ring a bell?

Surprisingly, yes it does. Ivan Pavlov (originally spelled p a v l o v) spent years trying to prove his theories regarding stimulus-response. He had little success until he began using dogs. His famous papers, which were published in "Harper's Bizarre Stories" in 1887, proved to the world that living organisms such as Harvard beets, *okra and even mushrooms do not salivate when you ring a bell, but dogs do.

* Not to be confused with Okra Winfry, who often salivates when she hears bells. Wait, that's not right -- I was thinking of someone else. Never mind!
