Don Knuth, the world’s most frighteningly advanced computer scientist, used to send out cheques as rewards for finding bugs in his software (T_EX or METAFONT) or errors in his computer science books: US$2.56, or one “hexadecimal dollar.” (Errors in 3:16 Bible Texts Illuminated get US$3.16.)

He can’t send any more, though, due to international bank fraud: personal cheques are now obsolete as they’re ridiculously easy to commit fraud with. So he now posts a list of balances at the Bank of San Serriffe.

For your further amusement: Knuth 3:16.
