You know him as:
Luke, Phil and Claire Dunphy's youngest child
Why we like him:
Luke began his TV life as a sort of pint-sized version of his clueless dad, but lately he's become "Modern Family's" secret comedy weapon, alternately wise beyond his years and exactly in tune with what 12-year-old boys are like (See: interest in knives, large animals, etc.). The junior Odd Couple relationship between him and Manny (Rico Rodriguez) is one of the show's best dynamics.
Where else you've seen him:
"Friends With Benefits" (movie, not series) and a couple of commercials
