Perhaps a movie that takes place in two days. The first part of the movie would include the usual running gags and whatnot, with the usual story, but Phineas and Ferb get injured after their project disappears from the effects of Doof's latest Inator. The second part would have Phineas and Ferb recovering in the hospital. Their friends would attempt to do a project for Phineas and Ferb and show them what they did on video. Doof would, once again, come up with an Inator that somehow makes the project disappear, but not before its captured on video and shown to Phineas and Ferb. Candace would try to bust them by telling their mom that the things they do are extremely dangerous and probably caused their injuries. Issabella would be extremely worried about Phineas and stay by his side for most of the time he is in the hospital. At the end of the episode, after watching the video, and because their injuries aren't that serious, they are let out to seize the day.

Phineas would explain the supposed cause of injury to the doctor and the doctor would say the "too young" line.

The credits would show Phineas and Ferb leaving the hospital, stretching, and Phineas saying that its time they get back to seizing the day.
