Last night, Donald Trump officially accepted the GOP presidential nomination at the Republican National Convention -- and the world watched in horror.

Trump spoke to the crowd for 75 minutes at the Quicken Loans Arena in Cleveland, Ohio -- and pledged to "make America great again" -- which basically seems to mean build a wall around the country so that Mexicans can't get in.

In the speech, the 70-year-old slammed Clinton's campaign slogan, saying, "My opponent asks her supporters to recite a three-word loyalty pledge. It reads: 'I’m with her.' I choose to recite a different pledge. My pledge reads: 'I'm with you' ― the American people!" He then went on to say, "I am your voice. … So to every parent who dreams for their child, and every child who dreams for their future, I say these words to you tonight: I’m with you, I will fight for you and I will win for you."

Oh god -- we hope not!

Hillary Clinton, Bernie Sanders, John Legend, Emmy Rossum and many other celebs were appalled by Trump's acceptance speech and took to social media.

In addition to the tweets, Clinton also introduced a "Trump Yourself" app, in which users can superimpose insults like "fat pig" and "slob," that the 70-year-old has hurled at people over the years, over their Facebook profile pics. As much as we love Hills, we may have to pass on this one ...

But ya know what we don't have to pass on?! Jon Stewart taking over the desk at the Late Show With Stephen Colbert to talk about the election, call Trump "an angry groundhog" and take down the Republican party's nominee. The former Daily Show host can't stay away -- and we don't want him to!
