A farmer was in a bar drinking and looking all depressed. His friend asked him why he was looking depressed and he replied, "Some things you just can't explain. This morning I was outside milking a cow. As soon as the bucket was full the cow kicked it down with his left foot so I tied up his left foot to a pole. I began to fill up the bucket again and he kicked it down with his right foot, so I tied his right foot to a pole too. As soon as I finished milking the cow again he knocked down the bucket with his tail and I took off my belt and tied up his tail with my belt. As I was tying up his tail, my pants dropped down, then my wife came out and well, trust me, some things you just can't explain."
