Frank Encarnacao (AKA Frank Cameron) is the actor who played Chick's doctor. He also played Dr. Mickhead on Scrubs.
When Grayson and Jules take Chick to the Doctor's office, before he bolts and runs there is a brief shot of the sign listing the doctors and it includes several names from the show "Scrubs" where Ken Jenkins (the actor who plays Chick) portrayed Dr. Kelso. The Doctors included Dorian (Zach Braff's character), Reid (Sarah Chalke's character), and Turk (Donald Faison's character).
To spoof the title which no longer matches the content of the series, in the second season the producers started adding self-deprecating jokes to the show's title card. The one for this episode reads: welcome to "Cougar Town" Remember when we wanted to change the title? Ah, good times. Thanks for sticking with us.
