Alexis Denisof is no stranger to avid fans of How I Met Your Mother. He has appeared in several HIMYM episodes as the annoying Sandy Rivers, who desperately wanted to be cozy with Robin Scherbatsky (Cobie Smulders).

"We were in New York and we snuck in through the back door to the bar where this show is conceived in and where the guys, the two writers (Carter Bays and Craig Thomas), used to go, and where it's set. In the show, it's called MacLaren's," Denisof said, describing the New York City bar McGee's.

How did the fans, who were unaware they were watching with HIMYM insiders and showrunners, react when Cristin Milioti was revealed to be the mother? "There was just this moment of silence and then the whole place just erupted. They were like screaming. The surprise and the relief. 'There she is!'" Denisof told PopSugarTV.
