During one period his father was housing a bear known as Terrible Ted chained under the building, the bear had had all of its teeth removed and Hart would sometimes as a very young child let the bear lick ice cream off his toes since he thought it was a good way to keep them clean.

Together they would often fight with Bret's two older sisters, Ellie, who was two years older, and Georgia, who was one year older.
