No, not that kind of spy!
The Wednesday of Holy Week is sometimes referred to as 'Spy Wednesday', indicating it as the day Judas made his arrangements in secret with the Sanhedrin to betray Jesus.
I came across this snippet of 'traditional custom' at Wikipedia: Poland: children traditionally hurled an effigy of Judas from the church steeple. It was then dragged through the village, pounded with sticks and stones and what was left of it was drowned in a nearby pond or river.
Being Wikipedia, there's always that element of doubt regarding the veracity of any entry - i this case, the reference linked to this custom is broken. So there's no way of knowing how ancient or recent this practice is.
It's been rumored that certain "reputable business" organizations celebrate Spy Wednesday by whacking an effigy of Judas, followed by dumping the body in the footings at a construction site or highway overpass, as fresh cement is being poured. :-)
