"Donald Tames His Temper". Using her purse, Daisy sweetly convinces Don of keeping his cool by bashing his skull against the floor. When his nephews take excellent advantage of their uncle's softened self, it's not long before the Duck's Berserk Button is finally pushed beyond what he's willing to tolerate, so he calls his girlfriend for advice:
Daisy: Why, spank them, of course! Be firm with them, but don't show anger!
Donald: Glory be! Then it's okay to whale the BLAZES out of 'em - If I do it with a smile!
Under this mighty tree of shade...I'll sit and sip my lemonade...''
In "Turkey with all the schemings", a hungry Don looks around his kitchen on Christmas Day, only to discover the awful truth:
Oh, me! Oh, my! I've spent ALL of my money, and there's nothing in the house to eat but a can of BEANS! This is a TRAGEDY worse than the burning of Rome!
The entire beginning of "The Secret Of Atlantis" may be the most hilarious exchange Barks ever wrote. Scrooge sends Donald to collect a debt from someone, promising to pay him half the debt as commission. Donald's thrilled, thinking of how big half a debt owed to Scrooge McDuck ought to be. Unsurprisingly, when he gets to the address Scrooge gave him, he finds he's at his own house — the "debt" was a dime Scrooge loaned him years ago. Donald goes back, pays his uncle with a quarter, and demands his change plus his promised nickel commission. After Scrooge gives it to him, Donald celebrats how he just "settled" a ten-cent debt for only five cents and is probably the first person ever to get a nickel from Scrooge McDuck... until he gets out to the street and realizes Scrooge paid him with a worthless, foreign nickel. Scrooge admits it but reminds Donald that he specifically said that coin "settled the debt," so Scrooge doesn't owe him anything more. Donald sulks until he gets home and his nephews reveal the coin is a rare antique worth five dollars. Naturally, the very next panel is Donald gloating in front of his uncle:
Donald: Have you ever been took! You didn't give me five cents, you gave me five dollars!
Scrooge:(in tears) For the ninety-ninth time, have a heart!
In "The Island at the Edge of Time", upon discovering how their jet went past the "international dateline" so that it's now Tuesday instead of Monday, Donald decides to use that fact to his advantage by telling Scrooge that he owes him another day's pay. Instead, Scrooge pays him "imaginary pay" for "imaginary time".
In "Donald's Snow Fight", there's a scene where the nephews fire a snowball at their uncle, knocking his pompous captain's hat off and leaving him with a ridiculous hairdo. He's not amused.
Gollum has nothing on Don's absolute lust for gold in "Donald's Gold Mine". Here.
"Sea Salts". Donald cannot reach a coconut's meat, so he urges his companion Bootle Beetle to retrieve it for him. The beetle goes inside of the coconut, ignores Don's hunger and has a feast. Don catches on, and demands to receive the remaining piece a.s.a.p. Said piece is too big to fit through the coconut's holes, so Bootle bites the sides so it gets smaller, to the point it becomes a pathetic, minuscule piece. Aware of his comrade's temper, he shrugs at the audience, throws the piece through the hole, and covers his ears. Cue Donald's furious squawking. Here.
In the same short, a now-elderly Donald learns he can't dance anymore...The hard way.
"Donald's Tire Trouble". The entire short is just watching Donald change a flat tire, but you'd be surprised how much his Hair-Trigger Temper makes it into such a huge ordeal. It gets especially funny when Donald gets trapped inside the tire.
