Consider the statement:
“John Goodman is Debra Messing’s half-brother.”
This can only be true because Debbie Reynolds played Dan Conner’s mother in “Roseanne,” and she also played Grace Adler’s mother in “Will & Grace,” though she had a different husband.
So . . . each player will name a cross-sitcom relationship, and the next player will explain it, and name a new one.
Valerie Mahaffey is John Mahoney’s daughter-in-law.
