Please Don't Chat With the Bus Driver

The bus is late, the queues are long, all the animals are waiting, some more patiently than others. When the bus arrives each animal is told in turn, 'Please don't chat to the Bus Driver'. But no animal can resist just a few words. Soon the bus driver is so busy listening that his bus is later than before, it goes the wrong way, it drives round and round the round-about and even hits a bush. When the battered, late bus eventually collapses, all the animals disembark and wait for the next bus. When it arrives they are told again - 'Please don't chat to the Bus Driver'. Guess what they do?
