S1·E14 Old Yeller

Transportation becomes an issue for the young couple when Greg insists Dharma can use his car any time she wants but makes compulsive demands on her treatment of the vehicle. (Dharma: ""Honey, I love you, but bite me!"") So Dharma goes to a city auction with Jane and Pete and becomes the proud owner of a 1968 yellow schoolbus. Meanwhile, Abby invites the Montgomerys over for a meat dinner, and reveals that she was once romantically involved with Salazar, the featured artist at Kitty's charity exhibition. An amused Edward challenges the Finkelsteins to attend the function, which is threatened by a freak rainstorm and flood—it's 'Old Yeller' to the rescue!
