The post on carnivorous sponges, specifically the lead author naming a species after his wife,
Named in honor of Eve Lundsten, beautiful wife of the first author whose commitment and support have endured through the years. Eve’s love for the Gulf of California also inspired this naming as the type specimen was collected. 
started me thinking about how I always acknowledge my wife in the acknowledgements of my scientific papers.
M.G.M. provided loving patience with the first author. 
So I began to wonder who and what else gets acknowledged for driving our collective sciences.
We thank C. Ancell for the excellent preparation; F. Jackson, M. Brown, Dead Lizard Society (MSU), M. Gardner and M. Ivie for their helpful comments and discussion; L. Hall for the illustration; M. Drool for inspiration; and M. Holland, R. Kambic, J. Li, E. Morchhauser, C. Wong and Project Exploration. 
An tasty acknowledgment to beer. M. Drool is Moose Drool brewed in Montana.
How about thanking those who have to put up with our language in the field?
We thank Baboon Teams 2009, 2010 and 2011 for putting up with AJC standing around and swearing at baboons a lot, 
We would like to thank the following people, mostly undergraduate students from Bloomsburg University, for their assistance in the lab at sea: Kory Angstadt, Dawn Bailey, Kimberly Baldwin, Peter Bernhardt, Mike Burczynski, Ryan Carr, Michael Diamond, Justin Derbes, Eric Drake, Raye Foster, Michael Fountain, Cindy Fraze, Marisel Gonzales-Bustos, Amy Harlan, Crystal Harlan, Mark Harlan, Katrina Hoffman, Adam Horovitz, Jennifer Hunt, Jason Kahn, Mindy Kelley, Jennifer Krapf, Amy MacFadyen, Nadia Meyers, Jerry Nettles, Aaron Norakus, Shawn O’Keefe, Jeff Perry, Tara Stoffel, Adam Thompson, Kate Treese, Chris Urie, Michael Weaver, and Adam Yauch. 
Or what about the people who care not to be associated with the work? This was apparently an April Fool’s Joke.
We would like to acknowledge the help of various colleagues in formulating this work, but they asked us not to because they didn’t want their names associated with it. 
Although not an acknowledge but a footnote. Taken on Sir Robert May in a croquet series sounds daunting.
The order of authorship was determined from a twenty-five-game croquet series held at Imperial College Field Station during summer 1973. 
An my favorite of all time
I thank the National Science Foundation for regularly rejecting my (honest) grant applications for work on real organisms (cf. Szent-Györgyi, 1972), thus forcing me into theoretical work. This paper has been circulating in samizdat since December, 1972, and I have given talks based on it before and after then. 
Each of these acknowledgments show the true side of scientists whether playful, passionate, or even frustrated. Scientists are inspired by the world around them sometimes this is the movement of insect across the forest floor and sometimes it is Sabotage by the Beastie Boys.
