Pharrell Williams recently dropped by Sesame Street to teach Elmo and Cookie Monster about the transitive powers of reading.
"You can go anywhere without leaving the chair by reading a book / You can be anything, a pirate, a king / Just grab a book," Williams sings on the uptempo "B Is for Book." "Pull a sword from a stone and wind up on a throne / Have tea with the Hatter, if he's mad it don't matter / Because he's inside a book." Williams then takes the two monsters on an animated trip to ancient Egypt.
This season has also seen singers like Gwen Stefani ("Be a Good Friend") and Nick Jonas ("Check That Shape," an ode to pentagons) visit Sesame Street, while on Last Week Tonight, the monsters learned about the dangers of lead poisoning from host John Oliver.
