WAM at stag, hen, leaving do's etc

I remember an article in Splosh magazine about a tradition in the printing industry where newly qualified printers went through an initiation ceremony where they were stripped naked, tied up and then covered in flour, eggs, milk, paint, glue, pee, etc and then left on display in public for a few hours.
Has anybody come across anything like this in real life?
I worked for a couple of years in a factory where there was a tradition where people were put under a shower on their last day or on a significant birthday etc. This tradition seemed to have started to drop off when I was there. The only incident of interest was when an attractive girl in her mid 20s left she was put under the shower on her last day and sprayed with shaving cream and silly string. She didn't have a change of clothes and went had to go home in a wet/messy state. I left a few months later by this time the shower had been removed, and rather disappointingly I was just presented with a present and card on my last day.
