Razors pain you;
Rivers are damp;
Acids stain you;
And drugs cause cramp.
Guns aren't lawful;
Nooses give;
Gas smells awful;
You might as well live.

 The most famous poet to commit suicide by gas inhalation was Sylvia Plath (1932-1963), who stuck her head in her kitchen oven on Feb. 11, 1963, and turned on the gas. The mistress for whom her husband, fellow poet Ted Hughes, had left her did the same thing in an apparent copycat act six years later. Decades later, her son committed suicide as well, by hanging.
