I have seen bits of the show, mostly because it is on opposite my favorite show (NCIS). Now, I have class on Tuesday nights, so I rarely get home before it's over. But I did see the bit about them "finishing" the marathon. And I remember distinctly saying to my husband that something seemed funny about that time.
And anyone who says they are "religious" when they are discussing something like this (a lie) makes me well, feel not very charitable.
