Your British boyf John Oliver reunited with his W-ORD co-anchor (probably the best co-anchor in all of television history) Cookie Monster to send the blue muppet off to the UK. Little does Cookie Monster know, there are no cookies over there across the pond. Just biscuits.
The clip is actually for The Furchester Hotel, a Sesame Street co-production for BBC's preschool network CBeebies that I imagine to be Downton Abbey but with muppets. But Elmo and Cookie Monster help out too. For the record, I could really get used to John Oliver teaming up with Cookie Monster on a regular basis. They could be the next Abbott & Costello or at least the next Peter Gabriel & Kate Bush.
