Character mistake: Erin is shown drinking an espresso in 5-25 "Café Disco". Later in the series in this episode, when Clark brings an espresso machine in that was given to him by Jan, everyone decides to try every flavor. In an interview Erin starts rambling but then remember the actual question she was asked, have you ever had an espresso before, she said she had not.
Continuity mistake: They take a pledge to "We all drink them all" referring to the espresso flavors. Angela puts her hand on top of the pile and it flips between Oscar's hand and Stanley's hand under hers depending on the camera angle.
Answer: In the 2007 episode "Ben Franklin" when Jim is talking to Pam there is a candy bar with a purple wrapper that says "Picar-" I assume picaroon, it's hard to see past Pam. I found this trying to investigate what that candy bar is lol.
