He also recalled the couple's first meeting back in college.

"I met her [the] first week of freshman year in college, you know?" he recalled. "And we didn't go out right away ... I was too nervous and geeky, no one would have gone out with me."

He shared they first saw each other in a stairwell, adding, "She was coming down the stairs to go out with some guy, and I was going up the stairs to see a girl, and we passed, not a word was spoken."

"I remember to this day, she had platform shoes on, bell bottoms, tight, and a glitter belt," he explained. "It was the disco era! And she is an amazing dancer, and she would look so cool and I was like oomp a doomp a doomp a doomp ... I don't remember anything, but I remember that."
