5:00 AM | Happy Math
(Click on the comic if you can't see the full image.) (C)Copyright 2015, C. Burke.I've done this. No, it doesn't make it better.

5:00 AM | Sherlock Pi: Irregular
(Click on the comic if you can't see the full image.) (C)Copyright 2015, C. Burke.Quit your groaning! You knew it was coming. I didn't disappoint.
