It's not easy being the younger brother of a ruthless prankster.
Tobias Mathijsen -- the Dutch filmmaker whose pink bedroom prank went viral last year -- is back again with a new prank in which he and his friends tilt his teenage brother's room 90 degrees.
Mathijsen and his crew go all out, mounting everything from carpeting to a desktop computer on the wall. As you might imagine, his brother is less than thrilled when he returns home.
The prank comes a year after the filmmaker turned his brother's bedroom into a room fit for a child, complete with bright pink walls and Justin Bieber posters.
Check out a time-lapse of the 90-degree transformation in the video below.
