I used to watch this British tv show where one person had to go on dates with three different people and choose one of them. The catch is that with special effects makeup none of the participants will look like themselves so it's literally all about personality. At the end once a "winner" is chosen the winner and the person who made the choice will reveal their true selves and decide if they want to go on another date. There seems to be an american version as well. Please let me know what it's called if you know!
