If you want to prank a male roommate and are prepared to work for it, remodeling his entire room and making it into a girly, pink princess chamber will do the trick.
According to the video posted above, Tom has been away for a few months and his roommates have pulled together to create the perfect prank for when he comes back.
They have documented the process of changing the room from a frat guy's to a girly girl's. They also provide before and after shots, and I can note that the bed, walls and drawers are all pink now.
The carpet has been changed to make it appear as though a four-year-old lives there. Last but not least, there is an actual dollhouse in the room.
Tom's reaction hasn't been caught on camera and I don't know if he has seen the room yet, but he should enjoy this prank.
