Right, but that doesn’t have anything to do with it. Regardless of her actual name, the kids were surprised when he said “that’s howimet your mother.” If the stripper’s name were Daisy and the mother’s name was Sarah, the kids would obviously know it wasn’t their mother if Ted had said, “I metastripper named Daisy. And that, kids, is howImet your mother.” They would just think “well that girl’s name was Daisy, so clearly it’s not mom.”
My personal theory: Her name is Tracy. In one episode, Ted meets a stripper named Tracy and then tells his kids “And that, kids, is how I met your mother” and the kids are shocked, saying “what?!??” Had the stripper’s name been something other than the actual mother’s name, the kids would have known automatically that she wasn’t the mother, making his joke not funny at all.
