Pope Francis showed his angry side while greeting fans at a stadium in Morella, Mexico, after an over-exuberant well-wisher tugged to hard on his robe and toppled him.
Sky News reported the pope's tumble led him to crush against a child for a few tense moments. The Daily Mail said he fell on a wheelchair-bound man.
Either way, the pontiff didn't appreciate the welcome.

He shouted in anger, in Spanish: "No seas egoista," the Daily Mail reported. In English, that means: "Don't be selfish, don't be selfish."
Sky News said the well-wisher, whose identity is unknown, grabbed him with both arms and wouldn't let go. Security rushed to help the pope, 79, get back on his feet.
The pope was in the middle of a six-day tour through Mexico due to wrap at a stop on the border with Texas, where he's due to lay a wreath to express his sorrow at America's failure to accept as many migrants and illegals as he'd like.
Republican front-runner Donald Trump, who's made a campaign out of pledging to crack down on illegal immigration, recently outed the pope for his highly charged politicking.
As WND previously reported, Trump called him a "very political person."
