Touch XKCD could not find any comic for this entry. This is either a bug, or Randall is using the XML-feed for advertisements again. :-D
I found this:

I started off with countless problems. But now I know, thanks to COUNT(), that I have "#REF! ERROR: Circular dependency detected" problems.

Touch the comic to read the TITLE-text. Rotate device 90° for wider view.

Which xkcd is the best?
