Boy - that song just gave me a flashback to an event of about 30 years ago. I worked as a filmmaker at an agricultural university in the midwest (USA). We would get calls to go and film happenings down at the barns.

I was my turn to film, so I went along to record semen collection from a prize boar. I was curious as to how they were going to proceed. I had grown up on ranchs in the west and had seen things done with cows and horses, but never with pigs.

They walked this big boar into a portable chute and lashed him securely to the side, which they then tipped over until he was laying on his side, squealling and farting! A vet then stepped up and gave him an injection which put him to sleep. Then came the amazing part (to me) - They shoved about a 3-foot black probe (rod) up the poor beast's ass, and then I noticed it had an electrical cord attached. When they turned on the juice, just briefly, that boar convulsed and spurted forth with about a quart of semen. I imagine you could call that an electric boar wanker ! Thanks (I think) for the memory.
