Puzzles in Real Time!

Puzzles in Real Time! is an April Fools' joke done by Stephen and Mal in 2015, in which they announce a new series called "Puzzles in Real Time" and then proceed to put together a 1000-piece puzzle in real time.

As they put together the puzzle over the course of six hours, Stephen occasionally films the puzzle close-up. Afterwards, bizarre and random things happen, including their clothes or the background changing.
