Guest Week: Zach Weiner (SMBC)

Guest Week: Zach Weiner (SMBC)

(alt-text)

Guest comic by Zach Weiner of Saturday Morning Breakfast Cereal. When I was stressed out, Zach gave me a talk that was really encouraging and somehow involved nanobots.

Guest week! Today's comic is contributed by Zach Weiner.
Five guest comics this week! XKCD should be back to normal after that.
