Jimmy Fallon is pretty excited for his debut on The Tonight Show. And maybe a little nervous, too…

“I’m freaking out right now,” the talk show host said when he called in to On Air with Ryan Seacrest. The two chatted it up about the very exciting opportunity ahead of Fallon.

“It’s so exciting. It’s crazy…This is the dream job,” he continued.

“Of course I’d loved to do it as long as people enjoy it. But I don’t see myself writing ‘Thank-You Notes’ when I’m 80 years old,” he joked.

Fallon’s so pumped for his debut that he took to Instagram to share a very special message with his followers, getting us even more pumped about tonight’s show.

“February 17, 2014 This is it. We are starting a new chapter of the Tonight Show. I can’t even begin to describe what we are all feeling right now here at 30 Rockefeller Plaza, NYC. But – I know that we’ll never have this exact feeling ever again. By this time tomorrow we’ll no longer wonder what it would be like to do the Tonight Show. We can’t put that feeling – that moment back in the bottle. All we can do is try to make the best show that we can and make people happy. And we will. Here’s to the first of many. Fun,” Fallon said via Instagram.
