PhD student at UEA is doing research into the theory that people's pets take on their behavioural characteristics. Eventually the sample comes down to three dogs, one belonging to a lawyer, one to a chartered surveyor and the third to a professional musician...

A bare room has bonio dog biscuits scattered over the floor at random, and the lawyer's dog is put in; it gathers up the bonios, divides them into two roughly equal piles and sits down exactly between them.
The surveyor's dog is put in, examines the two heaps from all sides and sits down next to the larger of the heaps...
Then the muso's dog is put in - eats the bonios, screws the other two dogs and says, "How much are we getting paid for this gig then...?"
