[Van Hagar]

My favorite was the one where Andy and Helen get trapped in a cave and heroic Barney organizes a rescue. They get out on their own, but realize what Barney has done, so they go back inside and let him think he rescued them.
Also love the one where the big city cops think Andy is a doofus because he is letting the crooks row off in a boat. Opie knows what Andy is up to, because the boat has holes in the bottom. Loved it when Andy put the uppity ones in their place.
