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.

It Is Pronounced Tro PAY: How many of you haven't pronounced his surname wrong at least once? If you say "I haven't", you're LYING!

At the same time, he has outright refused to do any request lines for Broly, because of the effect that Broly's lines have on his voice.
The multitude ways his last name has been (intentionally?) mispronounced.
