Since "Never Ending Gory" is rated R, Tammy, Tina, Jimmy Jr. and Zeke would not have been able to go and see it alone (you must be 17 or older to see an R-rated film without an adult accompanying you). However, it is possible that the kids lied at the ticket booth about which movie they were going to see.
During the scene in Tina's bedroom with the meat thermometer the door is open. In the next shot it is shown as closed. Later Linda asks Gene and Louise to leave the room and they do so through the closed door.
