I had to pick a point in Voodoo Walrus to start uploading from. I decided that starting right in the middle of some non-canon bonus content from last year was the best place.
Mainly because it has Mirth. And everyone loves Mirth. Even if they don't know who she is yet.
And to give a more substantial answer to the question that this comic was made for:
While Mirth's father has never truly appeared "On screen" as it were, he has left his mark on a couple of occasionally. Most notably for vague reminders: http://voodoowalrus.com/?p=980 and very interesting conversation with Mirth: http://voodoowalrus.com/?p=751
