It was the surprise of a lifetime when a group of eager Directioners saw "wax figures" of their favorite boys come to life in front of their eyes. In a preview to an upcoming episode of UK television series "Surprise, Surprise," the band played the ultimate prank on several lucky megafans at Madame Toussaud's wax museum in London. Watch in the video above.

One Direction will be immortalized in wax figure form (for reals) in 2013.

We saw the boys themselves get pranked on Nickelodeon this summer, orchestrated by a "pregnant" producer who convinces the guys that she's going into labor. Harry's horrified reaction is priceless.
