Truth be told, we're not so surprised by any of Donald Trump's antics anymore. 

But this incident right here takes the cake. The American national anthem starts to play but the POTUS is too busy being his usual bizarre self, beaming at himself, pleased as always. In fact, his wife Melania had to subtly nudge him so that he brings his hand to his chest. 

Watch for yourself:

Seriously, America? You voted this man to run your country?
