Considering that people have requested more of Grandpa Olson in the past, I think we're about overdue for a strip featuring him.
Interesting fact: I thought it was Tuesday twice on Wednesday. So as it turns out, when I was working on today's comic last night, I was thinking that I was getting the comic done a night early. But I guess it's a good thing that I felt like working ahead, because otherwise this would've been late. Somehow even with the semester started, I'm losing track of days. Weird.
