I don't find them funny, I find them interesting and useful. It's a discussion on interesting aspects of the Cocoa libraries. The common theme is that dirty minds could find the names of certain calls naughty. But it's not discussed or the point of the slides at least.

Seems like a reasonable talk. I was actually all set to defend the point of the author of the article, having read the article, but now seeing the slides I don't really see anything at all troublesome here. It's a valid tech talk.

But as you say, perhaps the video of the session would indicate the slides were ignored and it was a wild free for all of obscenities and bigotry.
