Today a good friend of mine told me the following story:
A coworker approached her and asked, "Do you know what a sheital is?" She nodded that she did, but wondered why her non-Jewish colleague was questioning her about the hair coverings of some Orthodox Jewish women.
He said that he had been riding the F train with his boyfriend when he noticed that several women in his car all seemed to have identical haircuts. He motioned to women of the Orthodox females nearby, who all seemed to be sporting the same severe, stiff bobs.
"That's because they're all wearing wigs!" his boyfriend replied.
