Oh, please. If you're going to rip apart 60's or 70's TV for continuity errors, or obviously being filmed on the Universal backlot, you're not even going to make it sporting.
Sheesh - how often did Wonder Woman, 6 Mil $ Man, or Bionic Woman claim they were in DC, but obviously were filmed in the hills around LA?

That episode was just on TV yesterday and you can tell she's in a water tank when she's supposed to be in the ocean. Lol
