While reporting from Boston on new bombing investigation details, Fox News reporter Mike Tobin — or, rather, his cheeks — were abruptly ambushed by two pursed-lipped live-shot invaders.

Fox News reporter Mike Tobin went on Bill O'Reilly's program Monday night to talk about the evil, violent union thugs who beat everyone up all the time. This is the same Mike Tobin who claims he was "hit" by protesters inside the Wisconsin Capitol a few days ago, which the magic of the Internet has since shown to be a questionable assertion. Still, Tobin sticks to his argument: Unions = Endless violence, everywhere. Bill O'Reilly, for his part, wonders "who's behind the chanting." Perhaps the Muslims? That's our guess.
