Riley has a basic understanding of plumbing, though nowhere near as advanced as his brother, Malley.

Riley and Malley tolerate DiNozzo, but even on three epilepsy medications, DiNozzo is too spastic for the brothers.

Note to all would-be kitten owners: If you get a kitten, get two. Trust me. Especially if you already have cats.
