there's some new cell phone company or something... they have cellphones for kids to keep in touch. They're basically walkie talkies that act as cell phones.
They only call each other and only have a radius of 1.2 KM or something like that... but have text messaging and voice mail and crap.
Anyway, this business suit guy approaches two kids and "ninja mom" jumps in about how they can't have cell phones and starts unleashing kicks and chops on the dude... who calmly blocks it all and says "step off ninja mom" and proceeds with his sales pitch.
It's so stupid but funny
