I love Paul Cat of the Alive and Young blog. I have loved him ever since reading his post, "Black & Tan: the Hypostatic Union of Christ."
He teaches, and as a teacher he is within earshot of a lot of young people, and many of these young people have a language impediment. They use foul language. He has come up with a discipline for such young people that may just nip the habit in the bud, so that there will be that many fewer adults out there sounding like gutter snipes one day.
