And they would have gotten away with it too if it wasn't for us meddling viewers. 

 

1. Ross's Ex-Wife Carol

Friends  

Ex-Wife #1 was only around for one season...so I'm not saying I care that much...But still. It was a formative season. We're trying to get to know the gang, get cozy, and then all of a sudden one of our favorite minor characters is replaced by a more-blonde imposter. I'm kidding, no one cares about Carol.

Little Freddy! This is what happens when you watch a kid character go through expedited puberty. The magic of television!

3. Vivian Banks from Fresh Prince of Bel Air

Fresh Prince

Aunt Vivian was the homie. We knew her and we loved her, but then she was replaced halfway through the series. That's three years of relationship building just ripped out from under us...I know I'll never be the same.

4. Morgan Matthews from Boy Meets World

Okay, to be fair, they're both little blond white girls and I may not have been able to tell the difference. Put them in some overalls and their hair in scrunchies and they're maybe the same person. But it's the principle of the thing!

5. James Kent from True Blood

Alright, once again, mad props for picking two incredibly similar-looking people. HOWEVER, don't think I haven't paid acute attention to their shirtless bodies and can therefore spot the differences. Because that's what True Blood is for, anyway.
