Where did The Blood Come From?

Two vampire bats wake up in the middle of the night, thirsty for blood. One says, "Let's fly out of the cave and get some blood."
"We're new here," says the second one. "It's dark out, and we don't know where to look. We'd better wait until the other bats go with us."
The first bat replies, "Who needs them? I can find some blood somewhere." He flies out of the cave.
When he returns, he is covered with blood.
The second bat says excitedly, "Where did you get the blood?"
The first bat takes his buddy to the mouth of the cave. Pointing into the night, he asks, "See that black building over there?"
"Yes," the other bat answers.
"Well," says the first bat, "I didn't."

Spencer Fullerton Baird

Died 19 Aug 1887 at age 64 (born 3 Feb 1823). American naturalist and vertebrate zoologist who in his time was the leading authority on North American birds and mammals. A pioneer in museum collecting and display, he was named the Smithsonian Institution's second Secretary upon the death of the first Secretary, Joseph Henry. Whereas Henry had envisioned the Smithsonian primarily as a research institute, Baird saw Smithson's gift as the means to develop a national museum. By 1878, Congress had formally given responsibility for the U.S. National Museum to the Smithsonian Institution. During the Baird years, the Smithsonian became a showcase for the nation's history, resources, and treasures. By the end of his tenure, the National Museum housed more than 2.5 million specimens and artifacts.
