I'm a carriage driver in downtown San Antonio, and of course almost everybody that I meet is an expert on horses. Last night, a girl came down to the stand and started talking to me about her horses. She said that she has a 27hh Arabian! No, that's not a typo; she actually said 27hh.
As soon as she said that, I started ignoring her, but another lady told her that there's no way that her Arabian was 27hh, because the world's tallest horse is only 20somethinghh, but she wouldn't listen.
What other crazy things have you heard people say about their horses?
