It was a big night for Donald Trump: his first major address to a joint session of Congress. His last big speech was at his inauguration and only clocked in at about 15 minutes, so Tuesday night's one-hour address was going to be a bigger challenge.

That's why he needed to practice beforehand. He was spotted in his limo going over what we assume were some tough parts of the speech just before he arrived at the Capitol.

So now everyone is giving the clip the caption treatment. The Daily Show even went as far as to dub the backseat practice session with Trump's infamous hot mic moment with Billy Bush.

More jokes with alternative captions and ideas about what was really going on kept flowing on Twitter.
