Olin Shivers wrote an acknowledgements section to his Scsh Reference Manual that worried his friends.
Acknowledgments should be filled with Thank you's and Couldn't have done it without you's. Olin Shivers acknowledgments section thanked no one. In fact, his acknowledgments section explains why people did NOT deserve his thanks, people like his parents, his graduate students, his colleagues. It's a rant only a mother could forgive...or maybe not.
