“think” they convincingly look and sound not chassidish
LOL. He is showing that Chassidim are human and fun and friendly by exaggerating his levush, singing in Yiddish, and stressing his tzebrochin Aynglish no matter where he performs. (If he is taking college courses in English it is so he can sing or even write lyrics in English and know what rhymes and what doesn’t – for instance, he could sing my “Food Shtemps far Alle Yidden” knowing he has to pronounce Tzu Drayt like a Litvak to get it to rhyme with Section 8 :)).
