NBC's breakout drama series, "This Is Us" just added "Emmy Award-winning" to its name, with guest star Gerald Mcraney taking home the award for Best Drama Guest Actor. The 70-year old actor played Dr. Nathan Katowski or Dr. K in the series, delivering two of the triplets of the Pearson family. In the premiere episode, he delivered a poignant speech about how Jack (Milo Ventimiglia) could create lemonade with even the sourest lemons that life has to offer. At the end of the episode, Kate (Chrissy Metz), Kevin (Justin Hartley), and Randall (Sterling K.

Brown) recited Dr. K's famous words that their late father passed down to them: "There's no lemon so sour that you can't make something resembling lemonade." It was for this role that McRaney earned his first ever Emmy Award, something that he never truly expected.

McRaney gets recognized by all walks of life

"This is Us" was last year's breakout drama series, giving viewers cliffhanger after cliffhanger on top of highly emotional scenes and revelations.

The show was so good that it earned not one but two season renewals at NBC. When it returns this September 26, the series will pick up where it left, with Jack and Rebecca trying to mend their marriage and the Big Three trying to get through life in their mid-30's. Dr. K was instrumental in the lives of all five major characters, and actor Gerald McRaney admitted to Gold Derby that "I’m getting now recognized by three generations of people, which is a little disconcerting to realize that that can happen. But yeah, it’s delightful to still be a part of the mix."

"This is Us" returns to NBC on September 26.
