Harry Potter and the Goblet of Fire
 The 40-Year-Old Virgin (Text)
 Alias (5x09 -- The Horizon)
These are from the most recent episode -- "The Horizon". This wasn't a very spoiler-y episode, so the icons themselves aren't very spoiler-y -- you can tell just by looking at the teasers.
The rest are at my icon journal, _rentalcar. It is friends/members only, so you must at least friend the community to see the protected entries. This is only a way to weed out hotlinkers. I didn't link directly to a locked post, so as far as I know I'm not breaking any rules.
