There are many situations in Hindi films where the hero comes in disguise to the heroine's house or vice versa. Sometimes the hero comes in disguise to kill the villain and his henchmen? And the dumb villain enjoys the song thoroughly. No wonder, with such low IQ they all get killed in the end.
There are many songs where the hero is in disguise of a girl or girls in disguise of a man, sometimes hero in disguise teasing the heroine. Many such song situations have given us many hit songs.
