If I didn't see the radiation symbol, this could have been an 80's sequel to the Twilight Zone invaders where a second spaceship was actually the final stage of a rocket which crash landed into a 80s Jacuzzi.
One episode I remember they took his gun away and issued him a lady's .22 pistol. His pinky stuck out when he pulled the trigger, and when he fired it the bullets didn't make it all the way to the target.
This was an awesome show and someone deserves to go to Hell for cancelling it.
There was a Season 2. And they completely retconned the nuclear explosion by saying Season 2 took place 5 years prior, even tho' that completely contradicted all of Season 1. It was brilliant.
This was one of two TV series that year to end their season with a nuclear explosion cliffhanger... The other one didn't resolve their way out of it with as much panache though.
Comedy, comedy never changes. The end of the world occurred pretty much as we had predicted: too many sight gags, not enough bombs or jacuzzis to go around. The details are trivial and pointless, the reasons, as always, purely human ones.
