U-Bet-Yer-Life-Insurance is a building that appeared in the episode, Chicken Poofs.
Timmy Turner and Cosmo chase Poof through here, trying to give him a vaccination for the "chicken poofs", a disease which turns people into chickens. Everyone in this office building also had a hawk with them. Poof ran around sneezing, turning all of the workers into chickens, who promptly fled for their lives from the birds of prey they had been keeping as pets.
The building is a tall, multi story glass building located in downtown Dimmsdale. Inside is an elevator, and dozens of office cubicles.
