The Executive Treatment is a tad funnier even though the plot took about 4-5 minutes to get started, so that episode gets my vote.
Is this one even a question? I mean, you're pairing of of S9's worst episodes with the third or fourth best. "Pull Up a Barrel" manages to be a creative episode with a surprising blend of story and comedy, and overall, gets my vote by a long shot.
Also, since 9B is longer than 9A, how will the late 9B episodes factor into this?
Pull Up a Barrel. I feel like this is an unfair pair though; Squid Baby isn't really that good, while Pull Up a Barrel is pretty good.
