The cast of “Sesame Street” stayed up well past their bedtimes last night to visit James Corden’s “Late Late Show.” The only problem was, they didn’t know exactly how to get, how to get to the “Late Late Show.”

Big Bird, Elmo, Grover, The Count, Oscar the Grouch, Cookie Monster, Bert and Abby Cadabby opened the CBS late-night show Thursday with a sketch of them performing a “Late Late Show” version of their iconic theme song “Sunny Days,” which started off with Big Bird entering CBS TV Studios and “12:30, everyone’s fast asleep.” Grover chimed in with, “Tucked in bed except one host we know.”

Then they ask how to get, how to get to the “Late Late Show.” And after a detour through “The Price Is Right” set and a taping of “The Bold & The Beautiful” with Denise Richards and Jacqueline Wood, the group finally makes it to Corden, who gives Cookie Monster a C-shaped cookie. (No, not for cookie, for Corden!)

Corden then takes his furry friends, who celebrate their 50th anniversary making kids smile this weekend, out on his stage to finish up their special “Late Late Show” song.

“Sesame Street’s” 50th anniversary special airs Saturday on HBO and Sunday on PBS.
