At approximately 06:38 of this episode (Soon after the opening credits) Lois hands Clark a box of glittery purple and silver decorations for Chloe's surprise 18th birthday party. At 06:43, Lois puts a rather large box of what appears to be paper plates, cups, etc. on top of the box of decorations that Clark is already holding. At 06:45 there is a reverse shot of Clark and the box of paper plates and cups is quite obviously not there anymore although the box of purple and silver decorations still is. At 06:48 the box of paper plates and cups has magically returned as Clark dutifully carries both into his barn.
