In addition to its reporting on the White House and other serious matters, the Washington Post runs something called the Style Invitational. The 1235th edition of this contest, running through July 24, asks readers to address the topic of science (broadly construed) in a song parody. So get to it, science songsters!
A quick Facebook exchange with Pat Myers, the Empress of the Style Invitational, clarified that previously written songs may be entered as long as they have not yet been widely distributed. For example, a song should not have appeared in a book or have thousands of YouTube views.
