Leave it to Jimmy Fallon to perfectly sum up just how incredible -- and exhausting! -- it is to be a first-time parent. In an adorable video for, the Tonight Show host dishes on life with 10-month-old daughter Winnie Rose (he mouth-breathes during diaper changes) and how excited he is to celebrate his first Father's Day (very).

But as funny as his stories are, it's co-star Winnie who steals the show. One look at the two of them in matching power suits, and it's easy to see why Fallon is so smitten. "I lucked out," he says. "I have the best girl in the whole wide world."

Check out the hysterical video below, including a not-to-be-missed shot of dad and daughter rocking back and forth in matching bucket swings.

Tell us: How has parenthood been for you and your partner so far? How are you celebrating Father's Day this year?
