I've got one:
Pit, Mario, Donkey Kong and Kirby are taking on Bowser and King Dedede, as Bowser and Dedede are kidnapping Peach, as well as a big stockpile of food (including DK's banana hoard). Bowser and Dedede have a cage drop down on the 4 heroes, activated by a trip wire. It catches everyone but Pit. Pit tries to help his friends, but Dedede comes and smacks him really hard with his hammer, and Pit is sent skyrocketing up to the heavens, with a comical expression on his face. He lands back in Palutena's home, but Pit realises nobody is there. Meanwhile, Bowser and Dedede are about to take off with Peach and the food, but a bright light blocks their path. It subsides, and then hearts form in Bowser's eyes. He then throws Peach and Dedede catches her. Dedede gives her a sleezy expression, while she gets all hot and bothered and starts beating him up.
It then cuts to Bowser running towards someone, but suddenly, he's hit by a staff. It then reveals the attacker to be Palutena, and she does her iconic head tilt:
"Palutena Graces the Battlefield!"
She then says "Sorry to keep you waiting!", and then cue the gameplay footage.
After the gameplay footage, it then shows Mario, DK, and Kirby free from the cage, regaining their bearings, and Bowser and Dedede comically knocked out, as Peach and Palutena high five with cute giggles. A water ripple effect happens, and the camera zooms out, and shows that Pit was watching through that...bowl of water he used to watch Mario and Kirby in the Subspace Emissary. He has a jealous looking expression on his face, because he didn't get to save the day. He then grumpily munches on a hamburger as the camera fades to black.
