Who is to say it’s not possible - technically.
My parents moved from Newark, NJ just before I was born .
Dad wanted to get out of NJ for some reason after living there for 6 years. Maybe he knew he wasn’t my “real” father.
Working nights at the airport - a young JJ slipping in the back door as dad walked out the front on his way to work every night. Seems about his style doesn’t it ?
