The Cameo Show

Cameos by actors from Newhart, Taxi, The Bob Newhart Show and Dear John highlight this bizarre episode which opens with a charity auction during which George wins a group-therapy session and Leo wins a van. George reluctantly visits the therapist and ends up working wonders on the group with his straightforward advice. Meanwhile, Leo uses his new van to run a taxi/tour-guide service and picks up a group of tourists who look strangely familiar. His passengers soon realize that Leo doesn't know the island very well and they are being taken for a ride.
