Hi Mom... Well, yes, I am working... Um, I'm a driver... No not a truck... Ambreed New Zealand introduced a go-cart-like machine for ranchers to gather sperm from bulls. A driver maneuvers the vehicle, designed to resemble a cow, so that the bull can mount it. The driver waits patiently until the bull is done and then drives away with the sperm so that manual extraction is no longer required.
What's scary is I sat here cracking myself up for 5 minutes thinking of cow sex / broke back / sperm based jokes until I realized how sad it is that I came up with so many...
