How to make corn on the cob?

Okay so, it's almost 3am n I am seriously craving some corn. Fortunately I found corn on the cob in the freezer BUT I never made it before! I have experience with canned corn but..yeah, don't have any. Can anyone tell me how to make it? Do I boil the corn in the water or do I boil the water first? I'm so confused! (> <)
