Hold this thread as I walk away
Watch me unravel, I'll soon be naked
Lying on the floor (lying on the floor)
I've come undone."
It's a law of cartoon physics (occasionally crossing over into live-action) that anything made of cloth can unravel into a single thread as though it were knitted like a sweater. Obviously more realistic (if you care about that kind of thing) when it involves an actual sweater, but even then unraveling a sweater typically isn't as easy as pulling on a random loose thread.
A variation of this trope concerns undoing a mummy's wrapping this way, usually causing the mummy to spin. Of course, this has the same problem in that a mummy isn't covered by one single long wrapping any more than a shirt is made of one single thread.
In especially cartoonish examples, this also applies to an animal's fur or feathers.
