When one of your mates gets hammered (either pissed or stoned or a combination of both..) and starts staggering backwards and forwards like an old decrepid horse.

Get the horsemug. Horses cannot be defined within any genus or indeed any phylum or taxonomic rank. This has led scientists to believe that they are either not of this earth (e.g. Aliens) or are man made. Recently the man made theory has been given more credit. In his book "Horses, why do we need them and Where are there beards" Dr Butterfield of Sheffield England stated "Only Cows and Pigs can be said to be related to Horses, and even they are nothing like them whatsoever" he also added "Horses and Pigs taste good, horses taste like shit". Conclusive evidence that they are not required and therefore man made. Although many believe him to be mentally disturbed Dr Butterfield did also come up with this interesting observation "If you take the head of a Donkey the legs of a zebra and the body of a Shetland pony you've basically got a horse". From this observation he also concluded "I think that there are people assembling them out of these component parts and selling them on the black market". Although all of these comments have been shown to be wildly inaccurate, nonsense and down right stupid it is all irrefutably true. No mention of beards was made except in the title of Dr Butterfield’s books. “This is more proof that it’s all true” he pointed out to an angry crowd at the fashionable horse fare shop in savile row in London.
