Speaking of, there was an episode of the 70s show "Emergency" (yes, I am that freakin' old

) where almost the exact same thing happened, except instead of water, there was either mud or soft dirt (or maybe the sinkhole was still caving in), because when Roy, Johnny, et al, got there and asked the lady if she was okay, she replied' "I'm slipping down!" It's actually a wonder that this doesn't happen more often, especially in areas where the mega-subdivisions of the late 1980's - early 2000s were built, and early on there were no regulations about bury pits, where contractors would discard excess material and debris. The stuff inside decays and degrades, leaving a big pocket of nothin', and one day, there goes half your house, or in this case, your spouse (sorry, I just couldn't resist

).
