Maltesers, BR delays and pigeons
Back in the day of British Rail I was stuck in Edinburgh Waverley one Sunday evening waiting for a very late train from Aberdeen to arrive. Being a somewhat poor student I consoled myself with a bag of Maltesers as I patiently waited for the damn train to get there. I dropped one of the Maltesers and it rolled off, a flock of the resident pigeons descended and they all took a turn at trying to grab it. Turns out the diameter of a Malteser is just too big for the average pigeons maw to cope with. The next hour and a half was spent replacing the eventually destroyed Maltesers with a new one as the increasingly deranged and belligerent pigeons attempted to grab these things, I was aching with laughing by the end of it.
