Haunted House

S1, E3: Bizarro - Johnny, the ghost, is getting careless. He fits in and out of the kitchen during family meals and makes continuous ghostly 'bumps' in the attic. When Roz sees Johnny invisibly lift the top off the chili pot behind them, she's convinced they have a ghost. Tom's skeptical, but Aunt Dolores suggests Roz call in a ghost exterminator, which she does - the flamboyant Dr. Malamar.
