Doug and Carrie find an old, unopened wedding present – a gravy boat – from Doug’s third cousin Ron and his wife Marcia. Little did they know that inside was a check for $1,500 that they never realized was there and therefore never cashed. However, because the check expired a year after the wedding, they ask Ron and Marcia to rewrite it. Though they initially feel they need to treat this unbearable couple to a few meals before asking in order to justify their actions, Carrie loses her patience the first time and she re-opens the gravy boat and “notices the check.” The plan backfires when Doug tells Ron and Marcia that they want to use the money for a trip to New Orleans and Marcia sets one condition – Doug and Carrie can’t go to New Orleans without them! Trying to avoid that debacle, Doug and Carrie attempt to sneak off to the Big Easy alone without letting their cousins know about it. Meanwhile, Arthur tries getting a comic strip he created into Playboy magazine, but his artistic talents leave a little something to be desired.
