Conventional Wisdom

(Historical Notes: These two got around a lot, and this wasn’t even the first time I’d seen random Yip Yips at a convention.  Also, I know I said I wasn’t even going to try to point out all the background cameos in these comics, but I do need to acknowledge Bug Boy from that one really early comic I keep saying I’ll be getting back to one day.  No, seriously, I will!  I’m totally gonna do it!

EDIT: Hey look!  Photographic evidence!)
