Continuity mistake: When the Clampetts are eating at the pool table, Tyler arrives and goes to kiss Elly May's hand. She flips him over and it appears that Tyler knocks a pool cue over on his way to the ground that was propped up against a wall unit. In the next shot, it is back in its place, and no one was seen to have picked it up.
Milburne Drysdale: I'm president of a bank.
Jethro: Wow, can I be president of a bank too?
Jed Clampett: Jethro that was a mighty disrespectful thing to say to Mr. Drysdale. Ask if you can be vice president.
Laura Jackson: What a stupid idiot.
Jed Clampett: Did you say something, ma'am?
Laura Jackson: What a stupendous intellect.
Jethro: That's cause I "grad-ge-ated" the sixth grade, ma'am. Only took three years.
