President Donald Trump had a harsh reality check while attending Game 5 of the World Series Sunday night. While the president is used to being flooded with well-wishers and adoring fans, in a crowd that isn't controlled by his campaign or the White House, things can get hostile.

Such was the case when about one hour into the game, a booming voice at the ballpark announced Trump and the first lady. The crowd erupted into loud boos and chants of "lock him up!"

The moment of realization was not lost on the president, who quickly turned from all smiles to a look of clenched anger.

The internet watched the scene unfold online, and eagerly chimed in with their own mockery.
