I forgot to post this yesterday. I’d other things on my mind. I imagine a few people weren’t quite sure if they were coming or going yesterday. 

A pun is a form of word play that suggests two or more meanings, by exploiting multiple meanings of words, or of similar-sounding words. I’m very fond of puns as it happens. But the pun here isn’t a very obvious one. Scale, in this context, is a synonym of climb: we climb mountains. But what do you do when you get to the top? You have to go back down and it’s probably not a good idea to waste too much time slapping each other’s backs at the summit. Why do men climb mountains? The facetious answer is: Because they’re there. It does seem like a rather weak reason for doing anything when you think about it. That’s the thing about climaxes. There’s nowhere to go afterwards but down or back.
