After under-performing in the ratings, Lifetime moved "Bristol Palin: Life's a Tripp" (Tue., 11 p.m. ET on Lifetime) to a later time slot, in the hopes it can maybe scrounge up some more viewers at a less competitive time.

This week, Bristol came face to face with a woman who impersonates her mother. Tina Fey may be the most famous Sarah Palin impersonator, but there are plenty others out there. This one even looked a lot like the former vice-presidential candidate.

The similarity was so striking, that a man walking by thought she was Sarah Palin, and started talking about how he'd supported her in the last election. But rather than set the record straight for him, the woman pretended she was Sarah Palin, right in front of Bristol.

Bristol was shocked that she didn't break the illusion, but maybe she just didn't want to shatter what was clearly a big moment for the man. Well, unless he or one of his friends he told about the encounter happens to see the show and lets him know he was duped.

"Bristol Palin: Life's a Tripp" airs Tuesdays at 11 p.m. ET on Lifetime ... unless they move it again.
