The Flintstones, Season 3 (1962)

Fred:
Hey, maybe a drink of 412-up will help! [Barney is still hiccuping] Hold it Barney! Here, drink this! [Forcibly pours the concoction down Barney's throat]

Barney:
Yuck! Woo, that tastes awful! I, uh, I feel kinda funny, Fred!

Fred:
What do you mean, funny? [Barney starts wobbling and making weird noises] Barney! What's the matter? [Barney disappears] Oh boy... Barney, where are you?

Barney:
I'm right in front of you! Boy, you must need glasses!

Fred:
Huh?

Barney:
That drink did the trick, Fred! The hiccups have completely disappeared!

Fred:
And you with them, Barney! You're invisible!

Fred:
I love my dear sweet mother in-law. My mother in-law is a doll.

Attendant:
Are you feeling alright, mister?

Fred:
Huh? Yeah. Yeah, I'm okay.

Attendant:
Good. Good. You just stay in here and rest. That hot sun out there is a killer.

Fred:
Poor guy, he must have been standing in it for hours.
