okay, so has anyone else been driven crazy by continuity lately?

lately, the whole age thing just drove me crazy. in 5x4 haley talks to peyton about being 21, but the in the whole 7 year itch episode, they made her 23, just so that they could say 7 year itch, 6 year itch just wouldn't sound good i guess. but then the next episode sam said that brooke was still just 22, when in previous seasons haley was younger, it for real got on my nerves.

it also took only one episode for peyton to go from a near flat stomach to looking 4 months pregnant!

i can't think of any more at the moment, but i'm sure that there are some. am i the only one who is being this picky or has anybody else noticed these things? if you have, what else have you noticed?
