Pardon?

The human auditory cortex is mysterious and complicated. What you think you hear has already been analysed for spatial information and enhanced and modified to conform to expectations of the listening context. The only practical application of this is that when you're ordering drinks you can say "salted penis" and the barman will invariably hear it as "salted peanuts".

There are another two standard bar jokes: At the weekend I ordered a round of drinks comprised of three different pints, three different soft drinks, and a bottle. When I finished reciting the order, the barmaid should have asked "in the same glass?". She poured all the drinks and asked me if I wanted a tray. The correct answer is always "Don't you think I've got enough to carry?".
