I remember a rather humorous incident at RAF Manston where a rather over-weight MOD Plod tried to chase after a local tomato grower who was attempting to nick buckets of foam during the clear-up hose down. Apparently one of the constituents of the foam was sourced from ox blood ... which worked a treat on tomatoes ... that is until an additive was introduced to prolong the shelf life of the foam ... which was poisonous to tomatoes ...
