What's the Difference? Round

For the What's the Difference? Round (WTD?) of each episode, the contestants are asked to "split some hairs" on the meaning between two terms "they might know nothing about." Each episode has a distinct special WTD? name. Some special episodes have repeats of prior WTD? or no WTD?. 
The various terms/concepts contrasted can be found on the What's the Difference? Round Terms page.
