Kind of a tangent, but I disagree with this part of the website Nick quoted:

"There are two things that need to be noted about anomalies in science. One is that scientists do not set out to look for anomalies. Anomalies hit them in the face. The second point is that scientists do not reject one theory in favor of another whose only advantage is the it explains an anomalous event."

Anything unexplained by current theories is an anomaly, and research scientists should be looking for them. And scientists should tend to favor the theory that explains an anomalous event, like Einstein's theories explained displacement of starlight during an eclipse, replacing Newton's theories in the early 20th Century.
