Uniform Stealing Board

Old Chinese comedy features a scene played for laughs. A man and woman are trying to escape some pursuers, so they knock out a passing couple and steal their clothes. The joke is that the man steals the female victim's clothes, and vice versa.

Starts at 37:30, disguise at 38:25. The real couple is discovered at 40:30.

I remember this from that departed Chinese video site. Fun reveal.
