Zoey's weird laugh

Lately, Zoey has been doing a goofy laugh in a deep voice. I caught it on video while she was looking at her picture book.

You can hear the laugh at 0:13. 

Also the reason she keeps making the "cheesy smile" is because I had the light on my phone on. So she thought it was the flash from the camera and she was smiling for the camera. :)

P.S. The weird noise at about 0:15 is the garbage disposal.
