What could go wrong?
"Um, it could be that they all got kicked out of school."
Well, if I remember the movie correctly ... I believe the epilogue indicated that John "Bluto" Blutarsky became a United States Senator, in spite of his 0.0 GPA after seven years of college. And, in the 2002 "mockumentary" film, Where Are They Now?: A Delta Alumni Update, it is revealed that Blutarsky eventually became President of the United States. Hmmm ... sounds an awful lot like Obama's history, except Blutarsky probably ended up with a higher GPA, abused alcohol rather than narcotics, and had sex with good-looking women instead of a harpy whose appearance makes barnyard animals look ravishingly beautiful in comparison.
So, all in all, doesn't sound like getting kicked out of school was too much of a downer for Blutarsky, eh?
