I wrote this a while ago but I found it very amusing. Houyhnhnms are a race of super-intelligent (and logical) horses in Johnathon Swift’s Gulliver’s Travels Part IV. 

1726 16hh jet black Houyhnhnm stallion. Beautiful, sophisticated black Houyhnhnm imported from the Land of Houyhnhnms. Learns very fast and is extremely, extremely, extremely smart! Be the owner of one of the most intelligent equids…ever! Huge personality! Very honest. Never spooks, very rational. Very clean – will pick up after himself and even help clean the farm. Enjoys deep analytical, logical, philosophical discussions. Will be excellent for the disciplines of debating, logic competitions, championship chess and other logic-based strategic activities. Excellent for single philosophers, debaters, scientists, geniuses and self-proclaimed “geniuses” or anyone who enjoys intelligent engagement with a being in civil, rational ways. Fluent and literate in native language of Houyhnhnm, understands Yahoo Language (English variant) but generally does not care to speak it (though is able to). Prefers to communicate in Houyhnhnm.

Never gets attached to other herdmates. Never fights, is peaceful and nonviolent – believes everything can be solved with calm and logical thought. Is not easily distracted or moody. Detests displays of affection, finds it too primitive. Enjoys naturalistic art. For companion only (but not for hugging or lovey dovey things) – is 100% sound but constantly engages in deep logical argumentative discussions as a form of protest. For experienced people only as will get into a philosophical argument that rivals Plato every time something is asked of him. May not respect humans he does not know very well, assumes them as “yahoos”. Not to be stalled as he will scientifically and rationally figure out how to escape a barn and will be extremely cross. Not recommended for beginners, yahoos, bleeding hearts, emotional people or those who think or reason emotionally. Is ridable if one a Houyhnhnm whisperer (not to be confused with a horse whisperer) or has a IQ of 200 and exceptional arguing and logic skills who can convince him that it is perfectly logical and reasonable to have a yahoo on his back and physically exert himself. Can be gelded if you can convince him that it is a good idea – (he claims gelding is a profound inference with nature, especially for a fine genetic specimen such as himself). A great spouse replacement for an intelligent person who feels that his/her mate (or ex-mate) is irritatingly too emotional and also irritatingly not bright or logical enough.
