The Clampetts Strike Oil - S1-E1
Continuity mistake: As Granny is standing in the bucket cooling her feet, she looks at the man on the table, and has her glasses on. A second later they're suddenly gone.
Continuity mistake: Mr. Brewster's hair is parted on the left in three scenes in Pearl's parlor and then is parted on the right in one close up. (00:06:28 - 00:06:49)

Continuity mistake: Mr. Drysdale and Miss Hathaway are driving in a Dodge convertible. The back seat is empty. When they arrive at the Clampetts' mansion, a giant stuffed tarpon suddenly appears in the back seat.
Granny Learns to Drive - S2-E33
Continuity mistake: When Granny drives across the front lawn, the truck doesn't leave marks. When the motorcycle cop leaves, the bike leaves a clear trail.
Continuity mistake: Granny is chasing after Jethro with the intention of paddling him. She runs into the mansion and her blouse changes color from blue to pink (or is it white?) and back to blue again in the same scene.
The Rass'lin' Clampetts - S6-E22
Other mistake: When Granny throws the Boston Strong Girl out of the ring at the end, you can tell that the Boston Strong Girl is jumping to get over the ropes.
