[[caption-width-right:350:Grady gives himself a good talking to.]]

->'''Creator/RodSerling''': The name is Grady, five feet short in stockings and boots, a slightly distorted offshoot of a good breed of humans who race horses. He happens to be one of the rotten apples, bruised and yellowed by dealing in dirt, a short man with a short memory who's forgotten that he's worked for the sport of kings and helped turn it into a cesspool, used and misused by the two-legged animals who've hung around sporting events since the days of the Coliseum. So this is Grady, on his last night as a jockey. Behind him are Hialeah, Hollywood Park and Saratoga. Rounding the far turn and coming up fast on the rail is The Twilight Zone.

A jockey named Michael Grady (Mickey Rooney) is sitting alone in his room after finding out he's been banned from horse-racing for life for fixing races by horse-doping. All he ever wanted was to be respected. He curses a reporter who's written of his misdeeds in the paper. He drinks in his depression and thinks of what his life will be now. He then hears a voice. It's his alter-ego.

He argues with his alter-ego, trying to justify his life and his actions, even lying about his crimes. But the alter-ego knows better. Grady is offered the chance to change his life with one final wish. Grady says his greatest wish is to be big. After Grady wakes from a nap he finds his wish has been granted. He's instantly grown taller. He's "big".

Ecstatic, Grady calls his ex-girlfriend over the phone just to prove to the alter-ego that size actually does matter. She angrily wants nothing more to do with him. The conversation gets heated. He screams at her. She rejects him, but Grady remains undaunted. He boasts that he can find more girls that will actually appreciate him because of his newfound height. The alter-ego remains unimpressed, feeling Grady hasn't made good on any of his promises.

Grady, however, is confused and asks the alter-ego what he really is and what his business is all about. The alter-ego tries to explain to Grady in the most simple way possible. He's "the last gasp". The alter-ego then criticizes Grady for his dumb and "cheap" wish and gives him better ideas and suggestions for what Grady would've really wanted. The ego implies that Grady could've wished to win the Kentucky Derby or perform a heroic act, but as it stands, Grady wished to be a "big man". Grady objects, defending his wish.

A telephone call from the racing commission informs Grady that he has been given another chance he has been reinstated and can jockey again. We hear the alter-ego laughing mockingly. Why? Because now it's too late: unbeknownst to Grady, he has grown even larger, about 10 feet tall now not only too tall to ride a horse, but he barely fits in his own apartment! Grady screams "I'm too big! I can't ride!" Devastated, the now-giant Grady wrecks his room and pleads with the alter-ego, "Please! Please! Please make me small, please! I'll never ask for anything again. Please make me small!"

The alter-ego replies, "You ''are'' small, Mr. Grady. You see, every time you won an honest race, that's when you were a giant. But right now, they just don't come any smaller."

->'''Creator/RodSerling''': The name is Grady, ten feet tall, a slightly distorted offshoot of a good breed of humans who race horses. Unfortunately for Mr. Grady, he learned too late that you never measure size with a ruler, you don't figure height with a yardstick and you never judge a man by how tall he looks in a mirror. The giant is as he does. You can make a parimutuel bet on this, win, place or show, in or out of The Twilight Zone.
