Billy Connolly
I never liked him ever since he made that 'I wish they'd get on with it' remark to a live audience about the beheading of hostage Ken Biggley... He angered some of the audience so much that they walked out...
Many years later I read that he's got prostate cancer and parkinsons disease. There still seems to be a lot of life left in him though. I was browsing local events in my area and was amazed to see that he's coming to Nottingham arena with a live tour later this year.
Seems like he doesn't intend quietly fading away....
