The best NASCAR track billboard ever?

NASCAR is a sport full of double-entendres and this one in Charmin's is one of the better ones we've ever seen.

This is the billboard that's on the grandstands at Charlotte Motor Speedway this weekend. According to AutoWeek, it's a two race deal between the track and the company, which also has a "Stop Skidmarks" banner on the pit wall. Will it prevent drivers from peeling out of their pit stalls and laying rubber on the track?

Charmin is also handing out free samples. No word if CMS took the giveaways as an opportunity to save some money and not stock the track bathrooms.
