(Oh, and how's this for some amazing inside information? The band in Betsy's video was really the multi-talented editor Namrata Tripathi!)
I think in a celebrity death match (remember those claymation battles?) between Betsy Bird, of Fuse #8 (the unparalleled School Library Journal Blog) and New York Public Library FAME, and
Marian The Librarian (from "The Music Man")
Oh, that line "What do you want to take out?"
...Betsy would win. After all, she has those magic Caldecott flying gold seals with which she can blind Shirley Jones!
Enjoy the videos,
