Now, for a cold blast of reality. People engaging in that quaint folk ritual of drinking reindeer urine after the reindeer has consumed large quantities of amanita muscaria (an hallucinogenic mushroom that grows in the Arctic) frequently emit a distinct "ho, ho, ho" sound while under the influence.
BTW, this is the substance identified by the ancients as "soma". It seems that it is not destroyed or metabolised as it passes through the body to the kidneys, so it may be used repeatedly.
