Getting a slightly crushed foot cos your favourite cow got too close to get the carrots.
OK, the toenail will probably again, but it wasn't her fault - she just loves her carrots and I just didn't get out of the way...
OR
Getting a welly full of 'shud' - the official term for a mixture of mud and, shall I say, more basic stuff originating from a cow's backside.
OR
Walking through knee high snow carrying buckets of water cos the shed trough has frozen and the coos need a drink. Note, if you carry buckets of water through knee high snow 1) you have to do an impression of a Pythonesque silly walk, and 2) you have to carry the buckets above the snow and that is sooo painful after the first 20 yards or so.
