At 35:26 Wilson's left hand is at his side and two staff members walk past him. Immediately thereafter, Wilson's hand moves to his hip, and the staff members walk past Wilson again.

At 13:25, Masters identifies the chicken being chased by Wilson as an Austrolorp. Black is the only colour recognised American Poultry Association, and while black is the most common, they can come blue and white, as recognised in other parts of the world, including its native country.
