Michael Fassbender is an ’80s sitcom expert.

The Irish heartthrob, 42, stopped by “The Graham Norton Show” on Friday to promote the upcoming “X-Men” film “Dark Phoenix” alongside co-stars Sophie Turner, James McAvoy and Jessica Chastain.

During his time on Norton’s iconic couch, however, he showed off some impressive sitcom knowledge we never knew he possessed.

“Well, basically… I was obsessed with American television shows,” Fassbender revealed. “And for some reason, the tunes have always stayed in my head.”

Then, without any coaxing, Fassbender launched into his own renditions of the theme songs from “CHiPs”, “Magnum, P.I.” and “Knight Rider”.
