THAT'S IT!!!! I knew there was something bugging me about Sam's hair S4 and S5... I liked it S1-S3 when it was all curly. And for some bizarre reason, in S2, it's ridiculously greasy-looking. S3 is my personal favorite for Sam!Hair -- it's curly and CLEAN and sorta longer but he still trimmed his sideburns (there is something seriously wrong when a guy's sideburns on TV looks longer than the longest part of my hair...) IDEK! I just like S3 Sam!Hair by far the best. Although I do miss the S1 bangs even though they got a bit erratic.
