The scene: two children (Russell and Silas), each holding a partly opened pair of kiddie scissors, and, nearby, Dust Mite and parents (of the kids, not the Dust Mite).
RUSSELL (in a sepulchral voice, while swooping his scissors over Silas'): Could I mate with you?
DAVID (to Julie, sotto voce): Let's hope he refines his approach some in the next few years.
Russell later explained to me that the scissors were seagulls, and Dust Mite was their food.
Maybe we have been reading too many old Ranger Rick magazines.
