Cracking me up

Okay, so it's not that difficult to do. I admit the fact. Still, Sophia absolutely cracks me up pretty much all the time. Here is the most recent example. This happened about 40 minutes ago. My laughter is even distracting to me, so apologies for that. At the beginning, she's saying "March, march." Then when you can't see where her drumsticks are, she's knick, knack paddywhack, drumming three on my knee....enjoy the crazy. I don't have the slightest idea where she gets it.
