Bits of Me Keep Passing Out

Ford Prefect: You've just been through a matter transference beam ... How are you feeling?
Arthur Dent: Like a military academy. Bits of me keep passing out.

—The Hitchhikers Guide to The Galaxy, (Radio series)

Someone experiences temporary paralysis or loss of muscle control, but tries to carry on with what they were doing regardless. Frequently, Hilarity Ensues - people losing control of their extremities is natural Slapstick fodder. Can also be Played for Drama as a mild form of Body Horror.

The causes vary - sometimes it's an aversion of Instant Sedation, where a sedative spreads gradually through the body knocking out muscles as it goes. Otherwise, can be a result of a Finger-Licking Poison, or just someone sleeping at a weird angle until their arm goes to sleep.

It's almost never a stroke (which produces such effects in real life), because that's not exactly comedy fodder - as the trope namer for Narm demonstrated, this isn't an easy trope to Play For Drama. However, see I Can't Feel My Legs for a related dramatic trope.

Expect accusations of being drunk if the character starts schlurring their worthss.

See also Intoxication Ensues and Non Sequitur Thud, which can also accompany this.

An Incredibly Lame Pun from The Hitchhiker's Guide to the Galaxy is the Trope Namer (and page quote), but not an example.

It's dropped when he gets out of the jungle, presumably with him getting a replacement power source offscreen.

Plato's description of the death of Socrates mention the last moments of the philosopher:

"... and he walked about until, as he said, his legs began to fail, and then he lay on his back, according to the directions, and the man who gave him the poison now and then looked at his feet and legs; and after a while he pressed his foot hard, and asked him if he could feel; and he said, "No;" and then his leg, and so upwards and upwards, and showed us that he was cold and stiff. And he felt them himself, and said: "When the poison reaches the heart, that will be the end..."
