Oh deary me...someone is suffering a sense of humour failure.
Have you ever heard of Jackie Mason, a Jewish comedian who made the most self deprecating jokes?
There are jokes about different races and cultures in every walk of life. The Irish take the mick (no pun intented) out of the Kerrymen and the Canadians extract the preverbial out of the Newfies. It happens everywhere so get over it. I find humourless prigs most offensive, but I don't bang on about it!
I suggest that people with a selective sense of humour stay away from the humour pages in case they get offended. That is, of course, unless they are looking for something to moan about. I'd of thought their energy would be put to better use on a site such as this.
"A sick sense of humour and proud of it!"
