It's Pope Francis as you've never seen him: a little ticked off. While the pontiff was greeting people Tuesday in a crowd in Morelia, Mexico, somebody got a little too aggressive after grabbing his hand and caused Francis to fall forward onto a man in a wheelchair, reports CNN. "Don't be selfish! Don't be selfish!" a visibly irritated pope could be heard saying in Spanish after bodyguards helped him regain his footing, reports ABC News. (More Pope Francis stories.)
