horse vomit

apparently, horses are physically incapable of vomiting because their breathing and digestive apparatus are somehow connected, or shared, or both, kinda like shared equipment preventing a man from ejaculating and peeing @ the same time.
when i made this comparison, the radio station intern asked if women could.
i had to stop and think because i've certainly never tried, but i believe that it is possible for a woman to orgasm and pee simultaneously.
am i wrong?
if so, tell me, because i don't wanna lead the poor intern astray- he already seems to be lacking in sexual experience and i wouldn't wanna feed him incorrect info about female anatomy...although, if i'm wrong and try to right it, that involves telling the intern i was wrong, which i also don't wanna do...
there are also (apparently) more horses than people in mongolia, so i may consider moving there, depending on how few people we talking about. and weather permitting, of course (which i suspect will be more of a problem than the horse:human ratio).
walk good.
