This is such a corny long ago movie for me. I haven't seen it before since 45 years ago. But every minute the ghosts are on screen they reverse a rule they made before. They can walk though objects and walls, but they can pick them up, too. They can touch people and move them or be felt. Lou and Bud have a lot of slapstick together while Horatio haunts the house, so who says they weren't working as a team. Hilarious, but a bit drawn out too long.
