2 people are talking to each other.

Person 1 'Do you know John?'
Person 2 'John who?'
Person 1 'John, whose dad is a drug dealer'

In order for me to know who you are talking about you had to say 'John, whose dad is a drug dealer' I would not have known otherwise.

How would you say?
I would hate to be recognized by 'whose dad is a drug dealer'

Thanks in advance
