Okay, so it's shoujo-ai, but it wouldn't fit in the title. (Why is the title bar so long when they only give you so much space ..?)
The "Wicked" musical is still rocking my socks like nothing else--possibly because of the new, very grey spin on an old black-and-white classic, possibly because of the fantastic female leads, possibly because Stephen Schwartz is a master of cheesy-but-wholly-involving, I don't know. (For those unfamiliar, it's the story of the up and down friendship between the primary two witches of "The Wizard of Oz", superimposed over the story we're more familiar with.)
The enormous height difference can be owed to the way Menzel's Elphaba completely -towers- over Chenoweth's Glinda. Honestly, I think "Wicked"'s Glinda far more likely to instigate this sort of thing, but this quote originally from Elphaba's duet with Fiyero was too delicious to pass up. As is the song name in the title.
