After Ray puts the cake in his pocket, he can be seen to stand behind Debra and lean down. In the next shot, he is standing up straight and facing a different direction.
After Ray sticks his fingers in the cake, two small crumbs appear on the table. They disappear between shots and two larger crumbs appear in a different place.
When Marie comes in to ask about Debra's health, Ray is holding a doughnut in one hand and a plate in the other. When he says, "Good morning" to her, the doughnut jumps to the plate, which he is now holding closer to the table as he sets it down.
