Kicked off the show!
I remember one episode where a mother and her two obnoxious daughters admitted to partying with each other and being crazy... And then when the show came back from commercial break they were gone and Jenny said that they were kicked off the show for lieing and being fake.
I think this was a 2000, 2001 episode... But I'm surprised that even after that whole controversial secret crush episode murder dealy, that they still didn't screen people properly.
