I think the dedication was for Joseph F. Knipfing, and everyplace I can see lists Kevin/Gary's father as Joseph V. Knipfing. Unfortunately, I'm not 100% sure since I accidentally wiped it off my DVR because the credits ran a tad long and got cut off and when the prompt to delete came up I wasn't ready for it and *POOF*.
From this, I see a few possibilities:
- it's a grandfather (uncle is doubtful as it would mean two brothers named Joseph)
- I'm wrong, and it was F. and it's their father
- it was a typo (F is right above the V) and it's their father
