Mm.. quite funny episode, some real pearls were there. I love that kind of humor they have there. And again - fishing. No wonder why Teal'c do not like to go there. Anyway - the story itself was not worth much but the fun and little action and those bugs - oh, they made it so much better, added that kind of positive laughter what after so serious episodes is quite needed.
Also loved the way how that paranoic char was built and the way he first looked like noone and then turned out most of the episode in the end was just to get him - on that part, cleverly plotted.
