Big Bird, in intellectual attire (episode 3100)

"Tips for Tots" is an unproduced Sesame Street sketch written by Joseph A. Bailey from approximately 1975. The segment's intention was to teach children a complicated formula, using simple letters and numbers, which would then spark praise when the child is able to recite it to others.

In the sketch, Big Bird, armed with a piece of chalk, writes out the letters and numbers that make up Albert Einstein's equation for the mass–energy equivalence, E=mc².

Bailey submitted the script to Jon Stone, who enjoyed it and added a punchline. However, the show's Research Department passed on it, claiming the segment focused more on the equation itself and neglected to explain its meaning.
