On a recent broadcast of SBS's 'Magic Eye', Lee Hyori and Kim Gu Ra attempted to do some interesting couple yoga.

At the 3:05 mark in the video clip above, a female yoga instructor and actor Jung Gyu Woon first demonstrate how to do a certain pose in which two people form an upright square, or the Korean initial "?".

At 3:59, Kim Gu Ra and Lee Hyori are challenged to make the same pose. Lee Hyori hilariously covers her behind as she bends over and says, "Oppa, excuse me," apologizing for the awkward situation. With the help of the two yoga instructors, Lee Hyori is eventually propped up over Kim Gu Ra to make a perfect square shape.

As soon as the instructors step away, however, Lee Hyori and Kim Gu Ra seem to be a bit shaky, as the former laughs and the latter seems to panic while holding her up.

Meanwhile, Moon Hee Jun exclaims on the side, "It's 'Tetris'!" causing the set to burst in laughter over his silly observation.
