These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Mr. Magoo
He Really Can Act: In universe Magoo is actually an accomplished actor despite his visual problems.
Out of universe, Jim Backus sings a truly heartwrenching song in the Christmas Carol.
There were some even nastier moments in The Famous Adventures of Mr. Magoo. For instance, in the ones (very loosely) adapting Frankenstein and Gunga Din, they actually kill Magoonote well, technically, his characters; the concept of the Famous Adventures series was that Magoo was an actor appearing in stage play adaptations of famous stories at the end. ON SCREEN!
Tear Jerker: Young Ebeneezer's song in the Christmas Carol (which gets an equally—if not more—heartbreaking reprise by adult Ebeneezer later; bet you never thought Jim Backus would make you cry).
