U. of Chicago's Surprise Package for Indiana Jones

The admissions office at the University of Chicago has received an unusual package -- addressed to Henry Walton Jones Jr. (Indiana Jones, in other words). The package, as detailed on the admissions office's blog, included a detailed replica of a journal from a character in Raiders of the Lost Ark. The admissions office is still trying to figure out who sent the package, and why, and has posted some theories.
