Smallville" chalked up some of its best numbers since its last season finale, earning a 1.8 rating/3 share average in Fast National ratings from The Nielsen Co.

The jump might have a little to do with slightly weaker competition Friday night, but more with the fact that former "Stargate SG-1" star Michael Shanks popped in for a special two-hour episode.

In fact, "Smallville" got better as the night went on, starting out with a 1.7/3, and finishing with a 1.9/3. that was the highest rating "Smallville" has received this season, and is just slightly below the 2.0/4 it got in its previous season finale on May 7.

But the numbers are still weak for the show. "Smallville" is averaging a 1.6/3 in overnights so far this year, more than 33 percent off its average last season when it aired on Thursdays.
