19: George Clinton
I still wish it were true.
George Clinton is an American musician most famous for his funk music and wild hair style, which we see depicted in the comic. Apparently, Randall is (was) such a great fan of the man, he once started a rumor that he also has a University-degree in Mathematics. But he wanted it so bad to be true, Randall started to believe the rumor itself.
The mathematic equations on the board are Laplace Transforms for functions, by the way.
