I really don't want to get in the middle of any Clinton thing, but that is the correct form of "their". It's the possessive, in reference to the pancakes and their iron.
I thought about that later in the day... after this was posted here... that's why I didn't move it to any form of social media... although &'they are' iron could also apply... but the use of 'them' was more caught in hindsight... which is always 20/20 I'm leaving it up but it shouldn't be used... hahaha Chelsea got me...
WOW, CHELSEA! A BA FROM STANFORD, A MPHIL FROM OXFORD AS WELL AS A DPHIL FROM OXFORD AND YOU STILL HAVE PROBLEM WITH THERE, THEIR AND THEY'RE; YOUR PARENTS SHOULD ASK FOR THE MONEY BACK!
