If you thought inference questions were tough...

I remember those buggers in the GP comprehensions - the RJ papers would require you to draw all kinds of inferences from the placement of a comma, or a slight change of tone or register. But this takes the cake: the New Yorker's cartoon IQ test. There're 5 cartoons whose punchlines are incredibly obscure, and you have to pick a reason (out of 4 choices) why it's supposed to make sense. Don't be depressed if you don't score too highly.
