In this dull, dispiriting time we have to get our humour where we can find it, no matter in how unlikely a place it might reside. Thus, I was pleasantly surprised on two fronts the other day to find a delightful piece of humour, first because it was in the usually turgid pages of the Age and, secondly, because it was attributed to our normally lugubrious treasurer, Josh Frydenberg, who is not renowned for his side-slapping wit.
