'Who's Your Daddy?'
"House"-hold name: D.B. Sweeney as Dylan.
"House"-lights: Dylan, an old band-mate of House's, has a new-found daughter Leona who was a victim of Hurricane Katrina and is now suffering hallucinations. House is sure Leona is scamming Dylan, but in the end when a paternity test confirms she is lying, House chooses not to tell Dylan because he sees how happy they are.
Out-"House": D.B. Sweeney is currently on "The Event," but we'll always think of him as Doug Dorsey from "The Cutting Edge."
