Oh if you were baptized a JW...I guarantee you they have a written record of the event. In fact everything that happens to you as a JW becomes part of your permanent record even after you are dead.
Nobody in the baptismal pool said anything to you except maybe "Hold one wrist with one hand and use the other one to hold your nose." Or maybe...come back here Spike...we need to dunk you again because your right leg from the knee up didnt get submerged."
