TULSA—In what was initially meant to be a gesture of unrequited love and devotion, Mark Brighton's elaborate 10,000-domino set-up spelling, "Marry me Jenny," failed to convince his now ex-girlfriend to spend the rest of her life with him. "Where are you taking me?" said Jenny as Brighton covered her eyes and guided her into the living room of his apartment where he had spent every night of the previous week meticulously setting up $400 worth of dominoes. "Mark, I'm not in the mood for this." Brighton then took his hands away from her eyes, tipped the first domino, and watched as his girlfriend broke down into tears and told him that she was unable to understand him as a person and had to leave.
