the dirtiest job I have ever done was working as a farm hand on my grandparents farm for a week. We didnt have to do any artificial incemination but my grandpa and I cleaned the barn by hand and that took about an hour, then we cleaned the chicken coop and we had to do some butchering too, then we had to round up the heffers and calves to give them their shots, needless to say when you are sort of running behind a herd of cattle in mud and poo you are bound to lose a boot and that is what happend to me. Grandpa and I also had to check the fence out in a bog, a very nasty bog at that. If you ask me if I would do it again I would say in a heart beat.
