Remove the real TV and replace it with one that looks exactly like the real one. The buttons have to be broken. Turn on something really embarrassing like porn or something (you can also video tape them doing something really embarrassing. Just say it is for the show) and turn it up really loud. Turn the TV off. Get glue and glue the plug to the outlet. Be watching them from another room or outside. Have someone's parents or boss come over for dinner. And when they get into the living room turn on the TV. And when they try to turn it off turn it up or change it to a different channel.
