A long time ago (somewhen in the 70's) I remember National Lampoon had a satire advertisement of the Volkswagen Beetle and how it floats and if Ted Kennedy had been driving one, then Mary Jo would still be alive.
On first read I thought the ad was legit but then I realized it was a spoof on Kennedy. VW didnt't see the humor and sued the Lampoon to remove it from the magazine.
Too bad I didn't keep my copies of the National Lampoon...
