My wife and I were sitting at a table at my high school reunion, and I kept staring at a drunken lady swigging her drink as she sat alone at a nearby table.

My wife asked,'Do you know her?'

'Yes,' I sighed, 'She's my old girlfriend. I understand she took to drinking right after we split up those many years ago, and I hear she hasn't been sober since.'

'My God!' says my wife, 'Who would think a person could go on celebrating that long?'
