Labor Pains - S2-E8
Continuity mistake: At the beginning during the bridge jump scene, the A-Team van changes. It suddenly has round headlights, its hub caps can be seen popping off when it lands, and it doesn't have any spotlights. The real van has double square shaped headlights, steel spoked rims, and spotlights. (00:05:20)
Gift Horse - S4-E5
Continuity mistake: After Iola gives Mama the tissue box, Mama goes inside and drops the tissue box and the tissue paper on the coffee table. The positions of both these things (and another knick-knack that was already on the table) change between shots.
