In honor of the 40th birthday of Sesame Street, the original version of the all-time awesomest Sesame Street song EVER:

(How does one spell MAN-NA MAN-NA, anyway? MAH-NA MAH-NA? MANNA MANNA? MAH-NUH MAH-NUH?)

(MUH-NUH MUH-NUH? MUNNA MUNNA?)

(doo doo doo-doo-doo)

(MA-NA-MA-NA!)

Happy Birthday, Sesame. Thank you for the many, many hours of joy, and for the many that you’ll provide to my kids.
