The Cannonball Run: RATED R VERSION

Rating: 10/10 (12 April 2005)

Does anyone know why all the DVD/VHS versions are rated PG?! I bought this movie on DVD (have it on VHS, rated R) and began watching it...After a minute or so I knew something was wrong. Checked the back of the box and it was PG! The 'R' version is HILARIOUS, and the 'PG' SUCKS! There are too many instances to count. The only difference is copious amounts of swearing, but it makes the movie SO much more enjoyable/funny.
"Nice car father...Thank you a$$hole." Or the PG "Nice car father...Thank you very much." <---A LITTLE different. "I can't see sh/t can you?! No problem man no problem!" PG-"I hope you can see more than me..." WTF?! I'm not going to list all the differences, but they are major. Anyone know where I can get the R version on DVD?! My VHS copy has seen better days, but I refuse to watch anything but the R version. Any help would be vastly appreciated.
