Final answer:
The question appears to refer to an entertainment storyline involving a character described as Joey's grandmother in wrestling. There is no well-known wrestling character by that description, indicating the need for additional context to provide a precise answer.
Step-by-step explanation:
The question, "Which World Wrestling character was Joey's grandmother?" seems to be referencing a specific scenario from an entertainment show or wrestling storyline rather than a factual event. It is important to note that characters in wrestling are often part of a scripted performance with unique personas and multiple storylines.
There is no well-known wrestling character that is commonly known as Joey's grandmother across the World Wrestling Entertainment (WWE) or other wrestling promotions. Without additional context, it's difficult to provide an exact answer to this question. If this scenario comes from a television show or movie, it might be necessary to reference that particular episode or script to find out more information about the character in question.
