Put a clove or two of garlic in the foil with the corn. Yummy.

Here's a tasty recipe for the grill:
4 potatoes, cut into wedges
2 ears of corn, cleaned, cut in half
2 medium onions, peeled, sliced
1 cup hickory-flavor BBQ sauce
1/4 cup butter or margerine, sliced into 6 to 8 pieces
1/4 cup green jalepeno sauce
4 cloves of garlic (or more)
Combine all ingredients in a large bowl and stir to coat. Place in a foil bag and put on the grill, turning every 10 minutes. Remove when potatoes are soft, about 20 to 25 minutes.
Then eat it with a dark beer. Smoke afterwards while hanging out with friends outside next to a fire.
