Full of Bull
Yesterday, my boss wondered how his nephew was such a good salesperson to our high-end clients. Well, first, he's young (ten years younger than me). Second, he's attractive in one sort of way. Third, he's a great bullsh-t artist. That man creates more bullsh-t than a field of cows.
That sounds impressive, until you think about it. Did you ever realize that all the herds of cows* you've seen are females? You can't gather bulls in a field because they'd fight with each other. I mean, I've heard of bulls, but never a herd of bulls.
