i usually bite in the skin and jus spit out the pieces, but this hurts my tooths

get an orange peeler, or just throw it at a wall until it cries and gives up and you win.

cut it into quarters

i do either this (sometimes sixths if its big) or i use my nail to slice into it a bit and then peel it.

Just eat it like an apple, peel included

I use this method

cut it in half then juice it.

Why bother, just shove your thumb in the navel and pull it apart.
