“careful”: “When I was in, there was an occasional re-baptism, most often because the person involved didn't understand what he or she was doing, sometimes having gotten baptized without having gone through the 80 questions first. At some of the big assemblies with 80+ baptismal candidates, some newbies just got in the baptismal line and got dunked.”
Maybe those youngins and newbies could use the defence that they had too much to drink before they spontaneously decided to cut into the baptismal line. I mean, sometimes that defence can be taken into consideration in court for certain crimes. (I showed up drunk at district conventions a couple of times, but I had already been baptized. Just say’n.)
