Quote from Frasier in A Passing Fancy
Frasier: The trick to remembering the difference between William Henry Harrison and William Howard Taft is a simple mnemonic device. Kirby: A what? Frasier: It's a trick. Harrison died in office after his first month, so we say "William Henry Harrison Was Hardly Healthy". And you can't spell "Taft" without the letters f-a-t. Kirby: So now to remember two things, I have to remember two other things. Plus the first two things. That's four things!
