This moment in time may have had Tom Pelphrey saying Bazinga.

Though his girlfriend Kaley Cuoco has a slew of iconic roles underneath her belt, one of her most popular to date would arguably be her character Penny from the CBS sitcom The Big Bang Theory. But as the Love & Death actor—with whom she shares 4-month-old daughter Matilda—revealed, though the comedy ran for 12 seasons, he may been one of the only people in the world not keeping up.

In fact, Tom recently shared that not only had he not seen the show, but he also didn't realize she starred in it. 

"Matter of fact, when I first brought Kaley to New Jersey to meet my family and friends, my mom's partner—who apparently was a Big Bang Theory fan—was there, and he kept calling her Penny," he told W Magazine in an article published Aug. 15. "I had no clue what was going on."

He added, "So I pulled Kaley aside, like, 'I'm sorry, I don't understand what's happening. Why does he keep calling you Penny?' She's like, 'That's my character in The Big Bang Theory.' I was completely unaware. I've watched a few episodes with her since, and, obviously, she's fantastic."

But it wasn't just the Big Bang Theory that Tom found himself catching up on starring his "abiding crush"as he also missed out on her early breakout hits, 8 Simple Rules and Charmed.

"I hadn't seen Kaley in anything," the 41-year-old continued. "Look, I live in a cave. Before I met Kaley, I was living in upstate New York, on a dirt road, in the middle of the woods, without much Wi-Fi. She's brought me into modern times."

As for the proof of those modern times? Keep reading for a look at their journey together a couple.
