Did Eugene Levy Lose a Bet?

I couldn't help but notice Eugene Levy once again reprises his "Jim's Dad" character in the next installment of the direct-to-DVD American Pie series entitled: American Pie: Beta House. This make Levy the only actor to appear in every American Pie movie. One has to wonder, what in God's name keeps drawing him back to do these tired, rehashed movies? One word: money.
