On Wednesday night, the Republican presidential candidate Donald Trump clashed with Democratic nominee Hillary Clinton in the final presidential debate.
Viewers believed Clinton won the debate by a 13-point margin, according to a snap CNN/ORC poll.
But even if Trump is trounced on 8 November, we might not have seen the last of him, as he refused to say he would accept the result. Here are three other times he acted like a toddler:
1. When he was still sore about losing
After Trump said he would “tell you at the time” whether he accepted the US election results (he is lagging in the polls), Clinton hit back: “There was even a time when he didn’t get an Emmy for his TV programme three years in a row and he started tweeting that the Emmys were rigged.”
Trump interrupted: “Should have gotten it.”
If he’s still mad about an awards ceremony in 2012, how long will he be thinking about the election 2016?
2. When he started calling names
Clinton said Trump would be a “puppet” for the Russian President Vladimir Putin
Trump barked back: “No puppet. No puppet. You’re the puppet. No, you’re the puppet.”
3. When he said the lady was mean
Clinton was talking about raising taxes on the wealthy – my social security payroll contribution will go up as will Donald’s assuming he can’t figure out how to get out of it.
Trump interrupted: “Such a nasty woman.”
