To prepare, rid the corn of the husk (the paper-like cover) and the silk (the white thread). Then bring to a boil enough water in a pot to submerge the corn.
Place the corn in the boiling water and cook in 5 - 10 minutes. Just periodically check the corn for your desired softness. Drain, then serve. Best with butter and a drizzle of salt and pepper. This got us through a lot of afternoons when I was a working student back in College. This, and banana cue :-)
