"You can't practice for this," Fallon joked about the carpet presentation. "I've been going to malls, rolling out carpet at Restoration Hardware."
In contrast, Fallon's whole career has prepared him for Sunday's hosting duties.
"We have a fun, surprise, pre-taped opening that is honestly cameo after cameo," Fallon gushed. "We've already shot half of it. It's so good! I won't say anyone's name -- Ryan Reynolds. I'm just so excited. I want you to see it."
Previous hosts like Ricky Gervais as well as Tina Fey and Amy Poehler have skewered stars in the audience, taking good-natured jabs at their expense, but Fallon says that's not his style.
