This year's other Ig Nobel winners include:
# PHYSICS: Since 1927, researchers at the University of Queensland in Australia have been tracking a glob of congealed black tar as it drips through a funnel -- at a rate of one drop every nine years.
# PEACE: Two researchers at Newcastle University in England monitored the brain activity of locusts as they watched clips from the movie "Star Wars."
# CHEMISTRY: An experiment at the University of Minnesota was designed to prove whether people can swim faster or slower in syrup than in water.
# LITERATURE: The Ig Nobel for literature went to the Nigerians who introduced millions of e-mail users to a "cast of rich characters ... each of whom requires just a small amount of expense money so as to obtain access to the great wealth to which they are entitled."
