Arthur & Co. think he's some sort of a insect.
"Let's cut it open and see what is inside."
"If I could get this helmet off, you would see that I'm a man. Does anyone here have a wrench?"
(Arthur to Merlin) "A WENCH? Well, as long as he doesn't do anything unseemly... Come here, wench!" (he commands to a passing servant girl.)
The astronaut has the girl hold his head/helmet in a headlock then rolls his body around, thereby unscrewing the helmet. The girl is left holding the "Head" (helmet) and faints.
Would you prefer the WENCH in RED
or the WRENCH in GREEN?
Red please
