In reference to this year's Indy Five Hunnert winner, "Worldwide Pants," is David Letterman's production company. Rahal Letterman Racing being the current team name.
When Pfizer entered Cup sponsorship with Viagra, the Company's management was concerned about the TV and radio guys messing around and generally screwing things up. Pfizer held very extensive training sessions for all the on-the-air talent that probably resulted in less air time and fewer mentions but kept Pfizer protected with the Food and Drug Administration and marketing practices standards. One example where not all TV mentions are necessarily good for the sponsor.
Which reminds me that I saw the Kingsford Charcoal sponsored Busch car catch on fire during the February 2003 Daytona race.
The latest lingerie sponsor seems to be Love Fifi:
http://www.lovefifi.com/Matt McLaughlin, the resident curmudgeon at racingone.com had this to say about Fifi earlier this week:
"...out rolls a new Busch series car sponsored by, I kid you not, "LoveFifi.com" I thought maybe it was a poodle breeding farm and I checked in to see if they offered target practice during certain hours. As it turns out LoveFifi.com sells ladies' undies. I want to know exactly how much they are paying Mark Green to drive the LoveFifi.com Chevrolet. Hell, I want to know how much they pay Chevrolet to allow one of their cars to race with LoveFif.com written on the quarter-panels. If Green were to win, an admitted longshot, I want to see him keep a straight face thanking LoveFifi.com. And don't tell me these folks aren't evil either. They're pushing lingerie in plus sizes. Plus-size women looking to get their mates amorous already have a sponsor in our sport...Budweiser."
