Sheldon: I kinda don't understand Transformers.
Dante: How so?
Sheldon: Well, they've established that they transform into a car or a jet or a houseboat, right? But then in the movie, they show 'em scanning an object and changing into THAT. So my question is: why be boring? Why not change into something new EVERY time?
Dante: Well... for one thing, it'd get old with your buddies.

Optimus Prime: Steven? STEEEVEN!
Steven: (as a trash can) HA! Down here.
