Paper-Thin Disguises

A horrible disguise. This disguise so, so fucking bad that it could make the entire audience facepalm or tell the villain/henchmen that the hero(es) is/are disguised.

Jeff:Hey look, the heroes are walking in with paper-thin disguises!
Henchman 1:Wait, what disguise? These must be the new guards.
Jeff:No they aren't!
Henchman 2:Look. That's the appearance of a new guard. You must be high again, Jeff.
Jeff:TOM I HAVE NOT TAKEN ANY DRUGS, ALCOHOL, OR ANYTHING ELSE THAT MAY DISTORT MY INTELLECTUAL COMPETENCE FOR 327 DAYS!
