As Seen In: Big Trouble in Little China (1986)
A helpful suicide handbook would have to argue that the task is best accomplished as quickly and painlessly as possible. A gun to the head, perhaps, or a lethal injection.
The apparently masochistic Thunder, in John Carpenter's campy genre smorgasbord Big Trouble in Little China, takes the opposite approach to self-termination. Sick of it all, he inflates his entire body into what's best described as a human hot-air balloon. Which, of course, ultimately bursts. Where's that handbook when you need it?
