Throughout the movies, cartoons, comics and tv series Spider-Man is shown walking on, hanging from and swinging from all sorts of structures, surfaces, ceilings and walls.
I understand how he does this but what I don't understand is how structures that where never built to take the weight of a full grown human don't ever suffer. I once watched a plaster boarded ceiling fall off from the weight of a light being hung from it (rather then being fixed to the beam like it should have been).
Has this ever been addressed in any medium, has Spider-Man ever gone to land on something, or hang from a ledge that couldn't physically take his weight and then fallen? Has he ever crawled across an office ceiling only to find that polystyrene tiles held on a thin aluminum frame really isn't designed to take a humans weight?
