“All of the sudden, he started bursting out laughing next to me, which is great; it really lifted my spirits,” Marcus explained. “I turned and thought, ‘Oh, I’ll grab my camera and tape it to send to mom at work.’ He just went crazy.”

The video was actually helped made famous by Alyssa Milano, who is pregnant with her husband David Bugliari. She Tweeted the video writing, “If this post doesn’t make you smile, check your pulse.”

Marcus says he only has one regret about the now famous video.

“If I knew this was going to happen, I wouldn’t have had him in his pink outfit,” the dad told St. Louis Today. “I’m going to have a lot of explaining to do when Micah grows up.”
