I know there were no unicorns.... the irish rovers said so.... but there were green alligators and long neck geese, humpty back camels and chimpanzees for sure.....
Now you are on to something. The unicorns were playing silly games with Bigfoot while all the others went aboard. If the Irish Rovers said it, good enough for me. Although they also sang coulda been the whiskey, might have been the gin.... and i think that explains most of the sightings.
