Knuth is also still reviewing TAOCP-related email and issuing reward checks. A teammate received a reward check for 1 hex dollar last month after finding an error in Seminumerical Algorithms. Along with the check, there was a printout of the original email with hand-written annotations.

Note that it's no longer an actual check --- instead one gets a certificate of deposit at The Bank of San Seriffe:

(I got a physical check for $2.88 for a typo and a point of improvement in _Digital Typography_ --- need to find another so I can get an account....)

If that was not included in your geography lessons see:

And one of my favorite quotes on the subject:

> Intelligence: Finding an error in a Knuth text. Stupidity: Cashing that $2.56 check you got.

Some of the checks added up to quite a bit more than that (if there's ever another error check for TeX it will be for $327.68), and one notable at a TeX User's Group conference stated that he had cashed a check for $40.96 and was grateful to DEK for it, since it put food on his table when he was a poor starving grad student.
