As I said:
See, when you have to explain a joke (as Slack made a pretty good joke), then the audience (that's you) is simply too dense to bother with -- and it's really unfortunate that both you and Dug are unable to have a bit of fun. Pity.
You'd actually understand what I'm saying, and that I *have* answered his request, if you weren't so dense - which is not my problem, of course.
I'll leave you to ponder that one, pal.
