Scrubs
For those who are unfamiliar with Turk and J.D., it's a bit of a pity. J.D. and Turk, the stars of the hospital sitcom "Scrubs," are perhaps the most endearing friends on television. While Troy and Abed (from "Community") and Joey and Chandler (from "Friends") are certainly beloved, J.D. and Turk hold a special place in our hearts. Their profound friendship blossoms in the hospital, where they both work as interns and surgeons.
If you're seeking a Halloween costume with your best friend, Turk and J.D. are an obvious choice. Thanks to their distinctive scrubs, they're also somewhat easier to recreate than, say, Joey and Chandler or Troy and Abed. In this instance, it's not just the clothing; somehow, these friends bear an uncanny resemblance to the show's actors.
