I was just talking about turtles with Spot. My Dad's hobby was raising Indian Star Tortoises and Elongated Tortoises. They are much smaller than the ones shown here, but we could see a scene like this virtually any summer night in our backyard. The elongateds were particularly funny. Our male tortoise was kinda randy and my parents nicknamed him "EverReady." So say you are a female tortoise and let's say you are tired or have a headache and you don't want to deal with the amorous intentions of your mate, what do you do? You withdraw into your shell right? But EverReady had a seductive technique to deal with such situations. He would lift his shell as far off the ground as he could and then start to rock back and forth. Then he would rear back and slam his shell into the female. Again. and again. Until the female couldn't take it any longer and got up and scurried away and withdrew into her shell again. This would repeat itself until she gave in and he was able to mount. Sometimes she scurry away in the middle of the mount and the cycle would begin again. When he mounted he stick out his very pink turtle tongue and shake his little head back and forth and make a sound like Aaaahhhhhhhccckkkkk. This sound and the banging of one tortoise shell against another was the soundtrack to a lot of barbecues when I was a kid.
