It's a funny thing...

...what goes through your mind the first time you experience car seat warmers. Having no knowledge of their existence you run though all the possibilities of why your butt is progressively getting warmer. Thinking you are going crazy and to afraid to say something to your fellow passengers you settle on the most obvious but least desirable question/conclusion. "What is going on? Did I just wet myself? Yup... I think I may have just peed a little."
