Who would've imagined that Bob Newhart would be trending on Twitter during Monday's College Football Playoff National Championship Presented by AT&T?

But it happened. And all because the lead referee for the Ohio State-Oregon matchup looks just like the famous actor.

Okay, yeah, the head ref does look like Bob Newhart. "He didn't make Master Tinker until he was 490." #CFBConGMA pic.twitter.com/scSv0pVV8n

And in this wonderful world we call Twitter, Newhart himself heard about the buzz and responded before the first half was even over.

In regards to my new career as head ref for #OSUvsORE - Hey, I don't have a series any more - I had to do something. #OSUvsORE
