I showed this clip to my class first day. The ingenious Sasha Baron Cohen playing Ali G and interviewing a (quite stern) Roman Catholic Priest, a representative from the Atheist Society, a Jewish Rabbi, and a university professor. It contains some pretty stupid humour [No surprise. Prof.], but I thought it served as a good example of a pretty accepting dialectic round table. ( And a few laughs .....)I like this Ali G best...
And from classfellow M.P., this:
[Mel Brooks' History of the World Part 1] .... is full of jokes against religion, but here are some links to the main points. I hope you enjoy them.
And of course, supreme is Monty Python's Life of Brian.
And here, courtesy of classfellow J.L., is a harsh and vulgar attack on religion: now that's polemic.
