In case you haven’t seen this yet: “Inception Ripped-Off Scrooge McDuck & The Beagle Boys!”
The work in question is a from Uncle Scrooge #329 by Don Rosa titled “Uncle Scrooge in the Dream of a Lifetime”:
Wikipedia (which we all know never is wrong) has this to say about “The Dream of a Lifetime”:
The Beagle Boys steal a dream making invention from Gyro Gearloose and use it to invade Scrooge’s dreams. Donald has to go into Scrooge’s dreams to get them out of there and they chase each other through different chapters of The Life and Times of Scrooge McDuck.
I’m not sold on this, as the comic book never mentions the kid from 3rd Rock from the Sun or the chick from Juno.
