Mr. Griffin Goes to Washington - S3-E3
Continuity mistake: When Mr. Weed is crying about losing his job, we see a view of a long line of trees in the window behind him. The camera switches to a close-up of Peter. When it zooms out again, the trees on the right of Mr. Weed are missing.
Suggested correction: I watched this part of the episode twice and no trees are missing in the window behind Mr. Weed after the close-up on Peter. Actually, Mr. Weed's head is covering part of the window where you can't see the trees on the right when he's lying on the table, but when he gets up you can see all the trees.

Other mistake: After the hurricane passes, Peter acts like he's been impaled by a wooden plank. He pulls it out as if it was attached to his right side.
