Awesome Bathroom Mirror Prank [VIDEO]

I love a good prank. Sometimes they're awful and should just be forgotten, but if you pull off a prank in the right way, it's totally worth the effort. I found this video and had to share it with you - they take twin sisters and place them on either side of a window in a restroom, so it looks like she's seeing a reflection in the mirror. As people come into this restroom, they see that she has a 'reflection' but they don't, which really gets a bewildered reaction from people.

Take a look and let me know what you think. I'd also like to hear about pranks that you've pulled in the past and what works as opposed to what doesn't! April Fool's Day is right around the corner!
