After dumping about $1.5 million worth of computer equipment into his alien hunt, his attorney advised him it was time to call it quits. He installed programs into all of the school computers so he could track radio signals that beamed any signs of extraterrestrial life. I think it's safe to assume that he spent every minute of his work day monitoring these radio frequencies, and the only thing he ever found was porn...which also didn't help his case to keep his job.
