Witness me avoiding "gnu" puns in my heading

Did you know a group of gnus is called an implausibility? Not that I'm likely to sees any gnus plural any time soon, but it's good to know that if I did happen to look out my window and spy them in my garden, I would be able to say, "Look! An implausibility of gnus!"

(On reflection, I think I'd be more likely to say, "Where did they come from?")
