I remember Vince teased him about it on commentary and Jerry would always deny it.I never understood why Brian Christopher and Jerry Lawler kept aloof about their father/son relationship, especially in the era of blending real life storylines into gimmicks. To my knowledge, they never worked a storyline together or ever acknowledged each other as father/son on air.
Taz is kinda doing that with Hook, but will at least acknowledge him as his son if it gets brought up. It’s pretty evident that he won’t be a part of a program with him, though.
