I liked this disclaimer

> Despite several rounds of revision, these notes still contain mnay mistakes, errors, bugs, gaffes, omissions, snafus, kludges, typos, mathos, grammaros, thinkos, brain farts, nonsense, garbage, cruft, junk, and outright lies, all of which are entirely Steve Skiena’s fault

(Skiena is the author of The Algorithm Design Manual which is a very popular algorithm book. Seems like he reviewed these notes :)

I like computer science books with a sense of humor in any case...
