F is for Flintstones.
Fred's Mother-In-Law's first name was unknown but her last name on the episodes she appeared in was "Slaghoople". On some episodes WIlma's maiden name was Pebble while on others it was Slaghoople. So this is an inconsistancy in the series.
Fred's great uncle, who owned a shack called "Sandstone Cemente", a pun on the California town, San_Clemente.(wikipedia
The flintstones live in the town of Bedrock. It gets its name from the fact that it is build on bedrock.
