more tea vicar?
boarding school, soggy biscuit................. once you've been involved in that particular game with your class mates I suspect that standing on a stage having a wank with or without a pigs head would seem pretty tame in comparison.I'm not sure it's necessarily immoral.
If the club required the initiate to stand on a stage and have a wank it'd be a bit weird, and probably not the kind of organisation that many of us would care to join, but immoral?
