Continuity mistake: Right at the beginning of this episode Kevin and the twins are making sandwiches. Lucy comes into the kitchen and kisses Kevin, then David asks where their (his and Sam's) kisses are. As this scene goes on, the shots ranging from views of all four to focal shots, David's sandwich is finished and on the (viewer's) left side of his plate, then unfinished, topped with lettuce instead of bread and on the right side of the plate. It goes back and forth between these two sandwiches. Also, at about 00:05:04 as Kevin and Lucy walk away, Sam's sandwich suddenly loses its top piece of bread. (00:04:40)

Trivia: This episode has the infamous scenes in which Mary wants Matt's help with kissing. Supposedly, the original script involved the siblings actually kissing for practice, but Jessica Biel (playing Mary) and Barry Watson (Matt) refused to do it.
