Wrinkled fingers test: another candidate for Ig Nobel Prize?

The pursuit of happiness in the form of a doctoral degree sometimes brings amazing results. This is another case of such pursuit:

UK researchers from Newcastle University have confirmed wet objects are easier to handle with wrinkled fingers than with dry, smooth ones. They suggest our ancestors may have evolved the creases as they foraged for food in wet vegetation or in streams.

Read the whole, it is highly educational. Methinks that to complete this worthy research, the scientists involved in it should add another experiment: check whether a finger that has been... er... sat upon for different periods of time facilitates handling of wet objects too.
