I wouldn't be surprised if Family cult members were part of this convention of "clowns".
The FCM, which boasts about 2,000 members around the world, is a nondenominational organization dedicated to "the winning of souls to Christ" using "sleight of hand, optical illusion, ventriloquism, puppets, balloons, clowning, juggling, storytelling, and other visual arts."
Yes, just like Jesus and his followers did, conning the gullible with illusions.
