Jim Parsons was a Danette for a day on Monday.

Jim Parsons of the Big Bang Theory is a big fan of the Dan Patrick Show and the actor earlier volunteered earlier to be an honorary 'Danette' for a day.

He made his way to the show today and is sitting in with Patrick's broadcast team (The Danettes) Paul Pabst, Todd Fritz, Patrick 'Seton' O’Connor, and Andrew Perloff (McLovin).

At one point of the show Dan Patrick is pushing Jim Parsons (Sheldon on the Big Bang Theory) to get him a guest spot on the show.

Patrick mentions Charlie Sheen and how he had interviewed him right at the start of the fight between Sheen and Chuck Lorre, the creator of both 'Two and a Half Men' (Charlie's one-time show), and Big Bang Theory and how that .

"You didn't instigate that, did you?" Parsons asked nervously.

Patrick reminded Jim that it was on his show that Charlie first called in to vent on Chuck Lorre.

"You know I didn't remember that before I professed my love for the show," Parsons answered.

"I may have to go back to 'First Take,'" Parson joked.

The BBT actor had earlier revealed he switched from ESPN's Fist Take over to the Dan Patrick Show and became a dedicated fan.

And now a Danette for a day.
