Make sure your BBQ is on, and hot - 500 degrees is a good temp.
Discard husk, silk, and stem. Cut cobs in half, and boil for 3 minutes, or until cobs turn bright yellow.
Transfer cob halves to BBQ, turning every couple of minutes, until you get a nice char on all sides.
Transfer corn to cutting board; trim ends as needed. Stand the corn on one flat end, and quarter the cob, slicing downwards.
Smother individual ribs in BBQ sauce and serve.
