Bring a large pot of water to a boil. Using a sharp knife, cut each ear of corn inot 3-4 pieces, each about 1 1/2 inches long. Add corn to boiling water, and cook just until corn is tender about 3-4 minutes; this should not take much longer than the time required for the water to return to a boil.
Drain corn. Toss with melted butter, and season with salt and pepper.
Serve with lime wedges to squeeze directly onto corn.
