CREATURE COMFORTS: A flamingo lawn ornament finds relief from the heat in a spot for Nicor, a Naperville, Ill.-based natural gas provider. The flamingo enters the house, cranks up the fan and helps itself to ice cream, grilled shrimp and a few golf putts before spotting its fellow lawn ornaments gaping at the bird through a glass door. The theme of the spot from Hal Riney & Partners/ Heartland, Chicago, is "Energy from Nicor. Make yourself comfortable." Copywriter: Bob Rickert. Art director: Vince Cook.
