A Scotsman walks into the pub and soon a fly lands in his pint of McEwan’s and takes a sip. The Scotsman snatches the fly by the throat and holds it over the pint saying “Gee it up, gee it up” until the fly gives back the ale. That’s disgorgement.
After the disgorgement, a true Scotsman would have made the fly pay for the part of the ale that moistened his beak.
