"If you don't like it, I'll f*cking find you," he threatened, which caused Reynolds to step in.

He then went over to Scobell and gave him an encouraging pep talk.

Scobell was apparently inspired by the chat and finally delivered his line perfectly.
"Kraft Mac and Cheese. Help yourself. And never stop loving your parents," he said.
The hilarious duo will be starring together in the new Netflix movie The Adam Project, which is being released globally on March 11.
