There are repeated references to Ashton Kutcher's role in Dude, Where's My Car? (2000). In the Hitchcock episode, Kelso (played by Kutcher) tells the paper boy, "This is a case of mistaken identity", a phrase he used many times in "Dude...". In the episode "It's a Wonderful Life", Kelso's future wife says she'll be waiting in the LeCar. Kutcher's character in "Dude..." also drove a LeCar. Ashton also uses the line, "LeCar for LeZak," in Just Married (2003).
