BALTIMORE—His car in the shop, Balloon-O-Gram deliveryman Burt Girardi, 37, was forced to use public transit Tuesday. "Well, that was pleasant," Girardi said. "You haven't lived until you've sat on a jam-packed crosstown bus for 40 minutes holding an 18-balloon Birthday Bouquet while dressed in full Zorro regalia." Girardi added that teenagers today think they are so goddamn funny.
