While the Republican and Democratic National Conventions won't be held until next month, this year's presidential candidates are presumably locked up. Hillary Clinton is expected to be announced as the Democratic candidate, while former Celebrity Apprentice host Donald Trump is likely set to be the Republican nominee. During last night's episode of Late Show With Stephen Colbert, the talk show host took matters into his own hand to stop a potential Trump presidency, with the help of Quantum Leap star Scott Bakula.

Earlier this month, we looked back on the obscure Trump cameo in Bobby Brown's music video for "On My Own" from the Ghostbusters II soundtrack, but just a few years later, there was a much more obscure, yet timely reference to the real estate mogul in a 1992 episode of Quantum Leap. The episode features Scott Bakula's Sam Beckett as a New York City cab driver in 1958, who starts making conversation with a young boy about how there could be huge skycrapers in the Big Apple some day. Beckett learns after this boy and his family leave the cab, the the boy was none other than Donald Trump.

In a new sketch that was posted on the Late Show's YouTube, Stephen Colbert decides to put an end to all of this Trump madness by using his own Quantum Leap device, with a special appearance from Scott Bakula himself as Sam Beckett. After picking up the young Trump, Sam tries to correct the course of history by making a number of suggestions to the youngster, although it only makes matters worse, according to the computer "Ziggy." While this sketch is ultimately a humorous parody, it's also quite frightening to imagine these scenarios with Trump in charge.

Quantum Leap ran for five seasons between 1989 and 1993, which followed Sam Beckett as he leaped into the bodies of different people, in order to change the course of history for the better. He's joined on his weekly journeys by Admiral Al Calavicci (Dean Stockwell), who only Sam could see in the form of a hologram. Al was also guided by a computer device dubbed Ziggy, which would calculate the outcomes of the future based on the decisions Sam made.

While we'll have to wait until November to see if Donald Trump will be our next President, don't be surprised to see more parodies like this spring up. We've already seen what it would look like if Trump ruled Westeros in a Game of Thrones parody, so we'll have to wait and see what else comes up between now and the November elections. Until then, take a look at Stephen Colbert's Quantum Leap parody from last night's Late Show.
