In his spare time, Barney builds a sport car, which Fred finds dangerous to drive. However, he hears about the Indianrockpolis 500 race and thinking the prize money can be useful for Pebbles and Bamm-Bamm's student funding, he enters the race but since Mr. Slate is unable to give him a day off, he lies that he is sick. Along with Barney, they go to the race track without telling the wives, but Fred must enter the race under a false name: Goggles Paesano. But how can they easily fool Mr. Slate who attends the race, as well as Betty and Wilma who saw Barney waiving at the crowd, and knowing Fred can risk his life on a track where he drives like he's coming home on the freeway.
(Fred and Barney are discussing how they're going to race) Fred: You'll be pit man, the mechanical genius, and I'll drive. Varoom! Barney: Well, judging by the way you drive home on the freeway, you ought to do real good at Indianrockolis.
Betty: You know, Barney did the sweetest thing this morning. He let me sleep, and when I woke up, he'd already gone to work. Wilma: Fred did the same thing. Betty: I kind of missed Barney's usual early morning greeting of, "Good morning, Betty, and a howdy-do-do to youty-too-too." Wilma: Fred's a riot, too, with his early morning questions. "Wilma, where's my razor? Wilma, where's my morning grape juice? Wilma, where's breakfast?
(While watching "Goggles Paesano" drive on TV) Wilma: All I can say is that Goggles Paesano drives a lot like Fred coming home on the freeway.
(Wilma and Betty just discovered Fred and Barney entered the Indianrockolis 500) Wilma: Oh, let's get over there and stop them. We're too young to collect insurance.
(Slate approaches Fred a.k.a Goggles Pizanno) Slate: My name's Slate. Fred: (using an Italian accent) Uh...I'm Goggles Pizanno from the old country. Slate: You look just like a fella who works for me. Fred: He's a good a-man, no? Slate: "He's a good a-man, no" is right
(The race starts) Race Announcer: They're off! There they go! What a race this is gonna be. In the first turn, Rocken McShale has the lead. Limey Whitecliffs, Weenie Rockton, and Bruce Gravelway are tramping on his tail. Goggles Pizanno is Number 8, zig-zagging, looking for an opening. Pizanno drives like someone coming home from work on the freeway.
(About Fred/Pizanno) Race Announcer: Uh-oh, Pizanno's hit the turn too fast. I see it, but I don't believe it. He's actually driving on the side of the wall. (crowd cheers) Race Announcer: I've never seen such a display of speed and skill. He drives like-- Wilma: I know, like he's coming home from work on the freeway.
The title is based on the Memorial Day weekend classic The Indianapolis 500 and is one of the premier auto racing events.
Barney's car is called the Rubstone Special, a combination of Rubble and Flintstone.
When Fred and Barney area heading off to the race, it's nighttime. Then, when they stop at the payphone to call Mr. Slate, it's daylight. In the next shot it's nighttime, then in the next shot it goes back to daylight.
After Bamm-Bamm closes the door after going outside with Pebbles to play, Wilma compliments about Bamm-Bamm and Betty wishes Bamm-Bamm would be more careful with the door. After Wilma says "He means well," her eyebrows disappear.
