(as) tipsy as David's sow

obsolete slang Very drunk. The phrase dates back to at least the 17th century, and the "David" in question owned a six-legged sow. When he went to show his sow to others in town, he found his drunken wife sleeping in the pigsty instead. Do you remember last night at the pub at all? You got as tipsy as David's sow! Help him get home, will ya? He started drinking whiskey, and now he's tipsy as Davy's sow. You were as tipsy as David's sow last night, stumbling in here reeking of alcohol!
