In a video appeal for submissions, Hart says: "We have an idea that, in the video, instead of it just being footage of me and my mom, we also wanted it to be footage of you guys and your moms.

"We thought it would be a really cool thing if you guys came up with footage of you hugging your mom, kissing your mom, laughing with your mom, walking with your mom - something cool that just shows the love you have with your mom.
