Have you ever inserted any objects,props, etc into a scene that were an inside joke for a friend or family member that no one else would notice? In the movie or video game industry these are called "Easter eggs" ever done it ? If so, where?

Thanks for this question! There are a few instances where Lynn snuck things into the strip or referenced specific things. You can find a page of cool things here. Occasionally Lynn would mention old friends by name in the strip, like this one with the Wildgrubes.
