Richard Dawkins and Cardinal George Pell answer questions about religion's truth and benefit to the world. <-- (link)
At one point in this Q&A, Cardinal Pell starts to mention that he and some other clergymen were preparing some boys for communion or altaer service or something, and he no sooner gets out the "we were preparing the altar boys" than the audience starts to alternately laugh and boo. Then he tries to finish the sentence again, and the same thing happens. The moderator had to step in to make the audience let him finish his thought.
I don't think laughter at the goings-on between Catholic priests and altar boys is appropriate, but I suppose there's some ironic dark humor in Pell's choice of language. =/
