The Daria Annotation
The flower delivery service at the beginning is named "Petal to the Metal."
Quinn flips to the date May 12th on the calendar. Taking that as the date of the anniversary agrees with the timeline set by "Fizz Ed", but places their first date in November, which doesn't agree with "Is It Fall Yet?"
The name of the dot com Jake gets a job at is Buzzdome.com, which is probably a play on the buzzword-laden speech everyone there seems to spout.
When Jake and the CEO order Kambuja, they never fill their glasses before drinking.
Kambjua doesn't seem to be a drink of any sort, but is rather the modern name for Cambodia. A macrobiotic place may well use this as a name for some custom blend.
Jane's favorite song is the theme to "The Poseidon Adventure."
The non-anniversary is an obvious play on Lewis Carroll's unbirthday scenes in the Alice stories.
