The secret to MBC's 'Real Men' filming has viewers snickering! Two photos from the filming set of 'Real Men' were recently revealed to the public.

The first photo shows the members being filmed on a staircase - but the bizarre thing is, even the camera crew seem to be wearing the army uniforms! 

In the second photo, Hyungsik was filming his solo interview. But unlike his full-uniformed top, he seems to have lost his pants and was wearing just his gray shorts.

The gray shorts are actually standard issue for the soldiers as active wear (such as when they're playing soccer during break), so he wasn't actually breaking any army rules. Hyungsik probably pulled the shorts on because it was too hot, but the difference in his top and bottom outfits has fans giggling, especially combined with his sad face.
