Here’s some background from The Biography Channel:

“Calvin Coolidge and his wife, Grace, were renowned animal lovers. Instead of a fruit basket or bottle of wine, a voter in Mississippi once sent them a raccoon to be enjoyed as part of their Thanksgiving dinner. The Coolidge’s promptly named her Rebecca and proceeded to take her on walks, at the end of a leash, on the White House lawn. President Coolidge was so enamoured of the raccoon that he built her a special house and visited her every day. What’s more, when the White House was being renovated and the Coolidge family had to move out for a short time, the President was so worried that Rebecca would miss them that he had a limousine sent to pick her up from the White House.”

From an interview with EVAN WILLIAMS, founder of Blogger, on Write the Web.com :

Q: Are you able to name any sites where you have noticed particularly unusual/interesting/different use of Blogger?

A: We tried to highlight such sites with our Blog of the Week, which features sites like “Who Would Buy That,” which, with much humor, highlights odd items for sale on eBay; the “Press Nothing to Continue” episode of 0sil8, which hooked up Blogger to “Tellme,” so you can listen to a blog over the phone; and “Presidential Haiku,” which features, well, haikus about American presidents.
