Feats of Strength!™

In 2000 BCE, Neal and George traveled to the English county of Wiltshire to participate in the yearly Feats of Strength!™. George lifted a cow (using his secret muscle enhancing device created, conveniently enough, by Neal and George years earlier, which was actually 1983 thanks to the time machine - don't think too hard about this, it might hurt your head). Not to be outdone, Neal lifted a cow and a boulder (he did not use the muscle enhancer; he's just that awesome). In disgust, George threw a boulder at Neal's head. Neal retaliated by throwing a series of rocks at George. This went back and forth for hours. After Neal and George called a truce - and after the townsfolk ran off in fear of being clocked in the noggin by a large rock - they rested on the piles of rocks they created, now called Stonehenge. Yeah, it happened just like that.
