Last year, people discovered that Arthur doesn't seem to understand how his ears work and can apparently hear sound through his skull.
Now people are wondering how he would wear glasses.
Because apparently he doesn't know how to hang them off his ears either.
Brian Jun, a 28-year-old Art Producer at Lab Zero Games in Hollywood, decided to settle this question once and for all.
This week, he tweeted out three possible ways that Arthur could wear glasses and it's been retweeted thousands of times.
The people kind of ran with it.
And started offering up their own theories.
They ranged from simple...
To, uh, elaborate.
He could just forgo glasses in general.
Or, you know, there's this thing called contacts.

Looks like we are having a problem on the server.
So, alright, let's settle this. What do you think? How would Arthur actually wear his glasses?
