I've been thinking, and reading, about folk etymologies lately. Interesting stuff. It tells you a lot about how the brain works, and how people are willing to believe the most appealing explanation.
Here are some examples.
Are there any others?? I think there are new ones popping up, but I can't think of any right now.
Oh: There is the one about goofy footed coming from a Disney movie. Although some people insist that is true, and Goofy does surf goofy in 1937's Hawaiian Holiday.
