Branson must be doing something right due to the huge success his airline has had.
It might not be in everyone's tastes, but it's AMUSING and it sells!! If the PC brigade got their paws on every bit of distasteful comedy these days, we wouldn't be laughing at anything. So wind your necks in and see it for what it is. Poor crew? What a load of old tripe!!
