Ultrasonic Velocity in Cheddar Cheese

Well you can't be serious all the time...
The 2006 Ig Nobel award winners have been announced. Like the Nobel prize, the Ig Nobel awards honour excellence in research and promote science and medicine, but with a focus on humour.
This year's winners include:

ORNITHOLOGY: Ivan R. Schwab and the late Philip R.A. May for exploring and explaining why woodpeckers don't get headaches.
NUTRITION: Wasmia Al-Houty and Faten Al-Mussalam for showing that dung beetles are finicky eaters.
MATHEMATICS: Nic Svenson and Piers Barnes for calculating the number of photographs you must take to (almost) ensure that nobody in a group photo will have their eyes closed.
PHYSICS: Basile Audoly and Sebastien Neukirch for their insights into why, when you bend dry spaghetti, it often breaks into more than two pieces.
CHEMISTRY: Antonio Mulet, José Javier Benedito, José Bon and Carmen Rosselló for their study "Ultrasonic Velocity in Cheddar Cheese as Affected by Temperature."
BIOLOGY: Bart Knols and Ruurd de Jong for showing that the female malaria mosquito Anopheles gambiae is attracted equally to the smell of limburger cheese and to the smell of human feet.
Congratulations to the winners!
