Nice guys!

I was getting a little concerned there that with all the views and no captions that the picture was just an in-joke to me or a tad too bawdy for the forum.

Since it kind of spoils the fun to explain the joke - instead, I'll just provide a supporting link to Brother None's amusing Let's Play of the River of Time on the Codex, where the answer (and Bogumil) can be found.

More pictures and captions welcome.
