DAGWOOD

I used the term "Dagwood Sandwich" recently and a young friend had never heard the term; I didn't even know if Dagwood and Blondie were still in the "funny papers";  yes, I learned that  Blondie is still syndicated.

Gerald said, "You have to be old to know the Bumsteads."

Naturally, that caused a flurry of "YOU KNOW IF YOU'RE OLD" examples.  The following list was compiled after a survey of family and friends:
