Robert Downey Jr. earned his first Oscar Sunday at the 96th Academy Awards.

"I'd like to thank my terrible childhood and the Academy, in that order," Downey said while accepting the best supporting actor Oscar for his role in "Oppenheimer."

He also expressed gratitude toward his wife Susan Downey and his stylist.

Earlier in the program, Jimmy Kimmel joked about Robert's history with drug addiction during his opening monologue.

“This is the highest point of Robert Downey Jr.’s long and illustrious career — well, one of the highest points,” Kimmel said.

Cameras then showed Downey Jr. double tapping on his nose, likely alluding to his past history with cocaine addiction. 

“Too on the nose? Or is that a drug motion you made?” Kimmel asked.
