Paul McCartney was awarded with an honorary music degree at Yale University last weekend.  According to sources at Yale who insisted on not being revealed, there was one unfortunate moment when Heather Mills showed up claiming she was entitled to half the degree.   When Mills was rebuffed by authorities, she eased her sorrows by disappearing into one of the frat houses, where according to the brothers inside she impressed an impromptu crowd with her “disappearing leg trick.”
