Burger King was the victim of hackers yesterday who changed their Twitter account to look like that of rival McDonald's. Talk about "college rivalry"!

Around noontime, BK's profile image was switched to show a photo of McDonald's new Fish McBites and the golden arches logo, with the caption, "Just got sold to McDonald's because the whopper flopped..."

McDonald's quickly said they weren't responsible, tweeting, "We empathize with our @BurgerKing counterparts. Rest assured, we had nothing to do with the hacking." But I am so sure they didn't hate what happened!
