Second Wife Second Thoughts

(My husband and I have been married for eight years. We’ve both been married before. I’m about to have surgery, and the nurse is confirming all my personal information. My husband starts talking to the nurse.)
 
Husband: “Wait, why does this say her middle name is Jane?”
 
Me: “What?”
 
Husband: “She doesn’t have a middle name.”
 
Me: “Um. Yes I do. My middle name is Jane. You didn’t know that?”
 
Husband: “You said you didn’t have a middle name!”
 
Me: “Wait a minute. [First wife] doesn’t have a middle name, does she?”
 
Husband: “…oh, s***.”
