Tow cable

You ever do something for so long that it isn't funny or clever anymore, it is just normal?   Years ago, right after Cars came out to DVD and we watched it constantly, James made a joke that we still use today.  We were out one day and I asked him if he had his keys so that we could stop and get the mail, and he said "I've always got my tow cable."  I laughed and asked WHAT??!!  So he explained that Mater says that to Doc during the dirt race between McQueen and Doc.  So, for like 5 years, instead of asking James if he has his keys, I always ask if he has his tow cable.  Will probably continue that forever....
