Bob's father says more than once that he has been married to Bob's mother for 45 years - but at the end of the show, he wants Carol to send his Mom a dozen roses because Emily's father had said she looks "great for 60", Carol says "what's wrong with that?" and Bob says "she's 56"........which would make her 11 years old when she married Bobs' father.
Bob is sending flowers to Emily's mother who was insulted by his father. The opposite was claimed in above statement.
