When life resembles a sitcom:

Mother and Father and toddler at dinner table.

Voice of preschooler, from the bathroom: "Could somebody wipe my butt?"

Mother looks at Father. Father looks at Mother. Mother and Father, while gesturing: "one, two, three..."

Father shows scissors. Mother shows scissors. Mother and Father, while gesturing: "one, two, three..."

Father shows rock. Mother shows scissors.

Rock beats scissors.

Exit Mother, to bathroom.
