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.

Yeah, this isn't one of your Klan rallies. https://t.co/ktd7w4LAGV

Welp.

Doesn't feel so good for people to chant to lock you up, does it?

It's more telling of the pulse of this country and how fed up we are with Trump that he's getting booed by a lot of white folks on the day that he announces the death of the leader of IS. #LockHimUp

I’m at the World Series. For the record, massive boos when they showed that fucker on the screen, despite them sandwiching him between shots of the military here. #worldseries #impeachtrump #lockhimup

– It's still only 10:15pm

This is incredible to see video of a sitting US President being clearly & loudly booed at the World Series.
Making America's Pastime Great Again! Nationals fans may have just taken the red hat back. #lockhimup https://t.co/crf3X1OBi2

You know Trump’s poor little ego was hurt with #LockHimUp chants. I mean seriously… Who stages a situation room photo, pulls out of Syria, asks foreign powers for help with elections, pulls out of global agreements, pushes through huge 1% tax cut and divides the nation like him

I have been pretty meh about the World Series this year. National fans you won me over. #LockHimUp

I have a shiny new red Nats cap that I bought in 2016 and have never worn because of the whole middle aged white guy in a red cap thing. These Nats fans may have just taken red caps back. #LockHimUp https://t.co/0UDDOY3AQ9

MLB fans skew older, whiter, and more male than other major sports. That makes the volume of the boos and prevalence of the chants tonight even more significant.

That should be his sweet spot.

America is waking up.#LockHimUp

I can’t scroll past a Trump getting booed at the World Series tweet without playing it with the sound on. Please keep sharing this A+ content. #LockHimUp

Our power is still out, so I won’t be watching game 5 of the World Series.
But I did see numerous videos of the crowd chanting. “Lock him up” about T*rump, so I didn’t miss the high point for me. #Trumptreason #lockhimup

LMAO. Reminds me of last year. Beach town I was visiting only has one coffee shop. Early AM waiting in line. Video clip of Trump comes on TV with audio off. Instantly, FUCK YOU's heard thru-out the shop. Middle-fingers fly. I fell in love with America again.

The American spirit is alive and well. He didn't change us, he just cheated to take power. A whole ballpark just chanted #LockHimUp!
