Baby Zebs is so tickled by her father's attempts to juggle that she can't help screaming with laughter -- and even toppling over in amusement.
In dad's defense, it must be hard to focus with all that adorable giggling going on. He explains in a YouTube comment:
I can actually juggle somewhat but I couldn't concentrate at all with her laughing at me. Strangely enough, when I do juggle (without dropping the balls), she doesn't really laugh at all. Must be something about constantly dropping the balls that gets her.
