Please tell me how you cook corn on the cob in the MW?

 I husk the ears, chill them, brush with melted butter, wrap with wax paper (twist the ends), and nuke on high for 7-8 minutes (4ears).  Comes out perfect every time.  pb

You can also wrap them in plastic wrap if you poke some holes in it, or just leave a layer or two of husks on them.  It only takes 2 -3 minutes on our MW.
