For every TV show that makes it onto broadcast (or streaming), there are countless others that went into development but were never aired. Some even had episodes ready to go before the plug was pulled. Commando Nanny sounds like it may have just as well been forgotten even without all the mishaps, since the trope of "family hires funny maid/nanny/butler who shakes things up" trope has been used a million times already. Others just sound like a bad idea from the beginning.
There are plenty of weird TV shows that we never got to see, and almost as many reasons for giving up on them. Read about 21, er, make that 20 of them in a Cracked pictofacts list.
Commando Nanny thats a name of a thing
