“D.P.O.”

Giovanni Ribisi and Jack Black showed up as guest appearances on the X-Files episode “D.P.O.” 

Ribisi is Electro, who loved video games at the arcade, attracted to his former special needs reading teacher.

Okay, he’s not actually Electro, but he may as well be. He was struck by lightning and survived and somehow gained some electrical powers. 

He was out to gain the love of his former teacher, played by Karen Witter. 

It was a pretty decent episode because you were never sure what Mulder and Scully could do against Ribisi. Because of that, the intensity of the episode was high.
