Kids Get Hilariously Honest When They Tell Their Dads Why 'You're My Hero'

The weeks leading up to Father's Day bring an onslaught of heartwarming and even tearjerking video tributes to dads. Now, writer and comedian Johanna Stein is adding a pinch of humor to the holiday.

To promote her new book, "How Not To Calm A Child On A Plane," Stein talked to some children at the playground, asking them what they've always wanted to say to their dads.

After a touching montage of "Dad, you're my hero" quotes, the kids start to get real. Hilarity ensues as they list all the things they learned from their dads, like "how to give the finger" and "the password to Mom's iPhone but not yours."

Dads, if you think you can handle the truth, check out the video and prepare to laugh.
