Herro

Listen here, pal. This joke plays on a stereotype about how some Asians pronounce "L" and "R" sounds similarly, so "Hello" becomes "Herro" and "eyes" becomes "eysh". The joke implies the person can't see their eyes, which is kinda dumb since everyone can see their own eyes when they look down, unless they fat like you. Face it, you probably can't see your feet either, you slob.
