I've lived in Dallas 10 years and can't stand the ticket. My wife's family think it's the funniest thing on the planet and call themselves P1s, whatever the frak that means.
The ticket reminds me of a 7th grade boys locker room. Sort of sports related, but nobody really knows what they're talking about so they resort to the lowest common denominator of humor. The last time I tried to listen to it, they briefly mentioned a Cowboys final score before going into a 20 minute segment about Leonardo DiCaprio getting drunk at a strip club somewhere, which led into the next segment where they discussed their favorite DFW strip clubs. Wha? Sounded more like National Enquirer radio to me.
My only explanation of its continual success in the ratings is not really an explanation at all. Witness the success of Toby Keith, reality TV, and McDonald's. Just because something is popular doesn't mean it's any good.
