Woody Harrelson joked about the plagiarism accusations against a "True Detective" writer while presenting an award with co-actor Matthew McConaughey during the 66th Primetime Emmy Awards. 

"I'm grateful you had all the plagiarized lines," Harrelson told Conaughey.

"Was that too much of an inside joke?" McConaughey responded.

"Okay, that was a little too inside," Harrelson agreed.

The two then moved on to presenting the award for Outstanding Lead Actor in a Miniseries or Movie, which was won by "Sherlock: His Last Vow" actor Benedict Cumberbatch beating Idris Elba, Martin Freeman, Billy Bob Thornton, Mark Ruffalo and Chiwetel Ejiofor.

Aside from the plagiarism joke, another thing noticeable with the two "True Detective" actors was their outfits.

Wearing maroon and navy suits, Harrelson and McConaughey channelled Will Ferrell and Chris Kattan who played brothers Steve and Doug in the 1998 film "A Night At The Roxbury," according to Perez Hilton.

Directed by Cary Joji Fukunaga, "True Detective" is about Detective Rust Cohle (McConaughey) and Detective Marty Hart (Harrelson) who are hunting for a Louisiana serial killer.  

Earlier this year, "True Detective" executive producer and writer Nic Pizzolatto was accused of copying portions of Rust Cohle's dialogue from horror author Thomas Ligotti's novel, "The Conspiracy Against The Human Race," the Independent reported.

In a statement, Pizzolatto denied the accusations saying, "The philosophical thoughts expressed by Rust Cohle do not represent any thought or idea unique to any one author."

"Rather, these are the philosophical tenets of a pessimistic, anti-natalist philosophy with an historic tradition including Arthur Schopenauer, Friedrich Nietzsche, E.M. Cioran, and various other philosophers, all of whom express these ideas," Pizzolatto explained.

HBO has also denied the claims.

"Exploring and engaging with ideas and themes that philosophers and novelists have wrestled with over time is one of the show's many strengths. We stand by the show, its writing and Nic Pizzolatto entirely," read a statement released to Hollywood Reporter.
