Tomboys don't get much shade thrown their way, so if the genders were switched in this video, a girl playing with her brother's Ninjas probably wouldn't care less that someone recorded the act. But a boy having a little fun with a Barbie? Well, that's a different story.
Probably the boy spotted his sister's doll on the table, and decided to make it stomp around like an action figure (his mouth seems to be making explosive sounds). Little did he know someone was watching.
The video is only nine seconds, but we are SURE you'll burst out laughing. And while we ALL agree that boys should play with whatever toys they want without shame, what makes this funny is not his embarrassment, but his all-too-human reaction when caught at the end.
