A show about two brothers being able to create amazing contraptions that are large in scale by putting their imagination to it is sure to have many of these moments.
- Anytime a celebrity guest appears on the show is awesome, even if it's for only a few lines. Ben Stiller and his wife, Kevin Smith, Seth MacFarlane, Jane Lynch, and Love Handel, to name a few.
- Slash asked them if he could do a song for the movie. That's right. THE Slash.
- Candace's determination to bust her brothers can lead to one of those.
- Anything Perry does when in agent mode, really.
- Phineas and Ferb in general are made of this trope. Some people dream of coming up with a genius invention even once. These boys do it every day.
