Dean Gardener, 19, and Jason Fender, 22, set upon the cross-dressing men shortly after being involved in another street fight in Swansea.
CCTV footage shows the pair approach one of the men – dressed in a pink wig, miniskirt and boob tube – before Gardener throws a punch at him.
But the fight is over in a matter of seconds as the other cage fighter, sporting a wig and a sparkling black dress, floors both the assailants with two lightning-quick punches.
One of the cross-dressers then casually picks up his bag before the pair strut off, leaving Gardener and Fender lying on the pavement.
The attackers are arrested by police as they stagger down the road. Officers later learned the cross-dressers were actually cage fighters on a fancy dress stag night out.
