People will believe just about anything they hear, especially when it comes to the names of Jay-Z and Beyoncé’s newborn twins.

A recent bit on Jimmy Kimmel Live used this gullibility to good effect, as they asked random passerby on the streets of Los Angeles to give a congratulations message to Jay and Bey on the newest additions to their family. There was one small catch, however: none of the names that were given to those who got on camera were real.
