He's awesome. I feel bad for him that he has to work. That really sucks. I wonder if he can read and write.

He's quite a hustla. I would assume if he can speak ten languages, he can probably write, too.

I bet he doesn't "know" each language... it seems to me that he has memorized a set phrase or paragraph about the product he is selling in each language.
Although it is still rather impressive and fun to watch

His pronunciation and fluency are outstanding. I teach English as a second language, and after 6 months some of my students don't achieve this level in just the one language. He's very talented. If he had been born over here, he could have been millionaire interpreter... or a millionaire hustler.

It fucking saddens me to see this bright kid subjected to have to work for a living. He should be learning in school.

Erm sorry bout that but his french, italian and german is almost not understandable. I guess it's the same with the other languages. But nevertheless you are right, it's a shame. And at least he is trying hard to make the best of it, quite a good approach in selling i guess.
