Show the Internet a green screen - and they'll get to work. The Olympic Games were no exception.

Earlier this week, after Imgur user factionman realized the tennis finals were being played in front of a giant "green screen", he decided to do some photoshopping. He showed the Internet what the tennis finals would look like if they were played in outer space, underwater and even on top of a volcano! Then other users joined the fun and started photoshopping not only the tennis finals but also weightlifting, diving, and more - all of which were filmed in front of a "green screen". Take a look at the results below and feel free to add your own photoshopped Olympics pics to the list!
