Move over, Snoopy. Take a hike, Dora the Explorer! This is Billy Eichner‘s Thanksgiving parade, and the floats must have Oscar’s approval.

In an exclusive sneak peek at the latest Billy on the Street, Katie Couric – a longtime fixture of NBC’s Macy’s Thanksgiving Day Parade telecast – joins Eichner, 37, to narrate an alternate version of the annual procession.

But instead of giant cartoon balloons, Eichner and Couric, 58, have invited only Academy Award-nominated stars to the party.

Rooney Mara, Sean Penn, Maggie Gyllenhaal and Mark Ruffalo are among the stars getting a helium high – because if you don’t think of turkey and Ruffalo’s Foxcatcher character Dave Schultz when you think of Thanksgiving, Eichner knows you’re doing it wrong.
