Ones that move me. Dark ones. I'm too serious for my own good so it's good for me to see silly eps, but they're not the ones I tend to watch over and over. I love Home and Faith and BUABS, Salvation and Shadow, Everybody Loves a Clown. There is humor in these eps, but humor is not the point, and I guess I like "funny" better as a spice, rather than the main dish. At least for SPN. :D
