Possible reasons this didn’t upload on Friday:

1. In an attempt to get a head-start on the clocks going forward this weekend, I overshot and ended up going all the way forward to Monday morning;
2. I decided to boycott Rebecca Black’s “Friday” by not doing anything at all on Friday. This included eating/breathing, and as a result I wound up in a coma for the duration of the weekend;
3. I wasn’t happy with Friday’s comic, so I delayed redrawing that particular one until a later date and did this one instead.

Take your pic!

I’m going for the second one myself.
