And no fake wrens either. Kill the wee bastards before they take over the world. Wake up, people! Didn't you see The Birds by Alfred Hitchcock? (I know, I know...it was by Daphne du Maurier.)
So let's get dressed up in outlandish clothing, get hammered and go round the houses and pubs on our sacred wren-elimination mission, before it's too late.
Ard-Macha, a chara, I believe there was a very similar tradition in your county with Mummers or Rhymers (the Armagh Rhymers) going out on St. Stephen's day for some and frolics. Not sure if there was a wren involved, though, I hope so. Vicious wee shites!
