I’m talking about a fan theory, that if true doesn’t drastically upend the fundamentals of the fiction it is set in.
Mine is that in the American Dad episode ‘Can I Be Frank With You’, that Snot’s uncle is actually just another Roger persona. He appears suddenly and conveniently to pitch a bizarre scheme, he loves hanging around with teen boys and doing drugs, and the very instant that the plan has a setback he kills himself out of sight of everyone else. That’s just Roger in a suit and glasses.
Edit: Ok, so, people are having trouble with the word “inconsequential”.
Skill issue! Nah, I have met plenty people that have the same reaction (English isn’t their first language). However, these sound are distinguishable by native speaker and will leave folks confused on occasion due to the ambiguity, or worse, hearing the wrong word entirely. The good news is that it can be learned and isn’t that difficult—you could probably pick it up from a video tutorial in a couple of minutes in your native language to which then it is just practice.
I am a native English speaker though…
That’s quite weird then since f & v, s & z, þ & ð are distinguishable sounds based on voicing. The only exception that is pretty wide spread for “th” sounds is in Ireland, but there is a quality difference is the aspiration between the two usually. Are you sure you are paying attention the vibrations of the throat?
