In this episode, it is revealed that Carly makes "special lemonade," which her friends apparently consider gross. This is a wink at another Dan Schneider show, Drake & Josh. Josh often made "limeade," which nobody liked.
After Sam announces her name and that she loves fried chicken, the next girl to announce her name says her name is Quinn Pensky. That is the name of one of the characters from another one of Dan Schneider's shows, Zoey 101 (2005).
