In Germany common name for a intoxication, It has been in use under "having a monkey (to buy)" since the beginning of the 19th century. The origin is not secured. Among other things, the phrase is due to the alleged alcoholism of the monkey. A second variant calls the similarity and thus confusion of the Czech terms "opice" (monkey) and "opit se" (getting drunk). And a third one says that this refers to the jugglers appearing earlier on fairs with a monkey on the shoulder.
