Modern caller ID and cell phones really date this film
This film is really dated, but nevertheless is fun to watch at least in one respect that it harkens back to a more "primitive" time, technologically speaking, when phones were rotary dial, and there was no caller ID where people could weed out the sort of prank calls those girls were making. Also, if the parents and kids each had cell phones, call waiting, text messaging, etc. etc., like they do nowadays, the parents wouldn't have had nearly as much trouble staying in touch with their kids, and wouldn't have had to call telephone operators and police departments to go check on the kids.
Fun movie, just awfully dated.
