Look, they make a triangle... That's actually really subtle by Smallville standards.

Crimson

Clark and Lois have a tendancy to mirror eachother's poses, although it happened more in season four than five and six. This scene in Crimson, however, is a prime example of that -- it's also really funny the way they just turn their backs on Chloe and Jimmy for no apparent reason. If you watch while Chloe and Jimmy are speaking in the forefront, you'll see Clark and Lois look back at them at roughly the same time, and then turn away again exasperatedly.
I laughed.

This scene always makes me wonder if Clark really does have feelings for Lois.
Way, way down.
Way down.
In a crevasse.

This shot (and a few that come after it, including all of those on the roof) is hilarious in its lack of subtlely. You have Clark in his most Superman-reminiscent outfit making out with Lois in a telephone booth*
at the Daily Planet. The camera even pulls back so you can see the logo on the wall, just in case you suffered some kind of brain trauma since the beginning of this scene and forgot where they were. They also threw in a little heart balloon for good measure.
Oh, Smallville.
* Does anyone remember that nineties song by the Spin Doctors -- Jimmy Olsen's blues? It's a fun song about the Superman/Lois love affair from the point of view of a Jimmy Olsen who is infatuated with Lois. One of the lines is "Lois and Clark in a telephone booth". This shot always reminds me of it.
