Continuity mistake: During the scene where Ned and Chuck are making a pie, Ned picks up the unfinished pie crust off the counter so Chuck can put more flour down. After she sifts the large pile of flour on to the counter, Ned moves to put the crust back down and now it is easily twice the size it was when he picked it up. There is no way for him to have rolled the crust larger off camera because Chuck was in the way and that was the whole reason he picked the crust up.
Continuity mistake: When Chuck blows away the powder, it leaves just the hand prints. When Emerson lays the sticky sheet down, the hand prints are gone and it's just powder again.
Continuity mistake: When Perry, the undercover busboy, has the pipe in him, you can see the rice in the opening (after it stopped pouring out). When he says Bao's daughter is the beneficiary, the rice is gone. It's back in the next shot.
