- Acting for Two: Thad and Chad are played by the same actor.
- California Doubling: Thoroughly averted; the series is both set and filmed in New York City.
- The Cast Showoff: It took a longer while to get there, but after almost six seasons, Broadway legends Sutton Foster and Miriam Shore, joined by pop-star Hillary Duff, get to show off their vocal chops in a rendition of "9 to 5"
- Season 7 has Sutton Foster dressed like a flapper and tapping to her cast recording of Forget About the Boy.
- Channel Hop: From TV Land to Paramount Network, starting with season six.
- Playing Against Type: This is the first full TV series to feature Hilary Duff in a regular role since Lizzie McGuire ended its run in 2004, and her role as the free-spirited Kelsey is, appropriately enough, a considerably more adult and kid-unfriendly role than Lizzie (or much of her roles at least up until War, Inc.).
- Playing Gertrude: Notably averted. You would almost expect a younger actress playing the part of a 40 years old woman who can pass as a twenty-something, but no, Sutton Foster is the same age as Liza.
- Recycled Script: The aftermath of Charles finding out Lizas secret plays out almost exactly the same way it did with Kelsey. Both treat Liza in a passive aggressive manner making veiled insults to her at work in front of everyone and both do come around after witnessing Liza with her daughter allowing them to see the real Liza.
