This phrase is from Sesame Street, a children's show created in 1969 that teaches literacy, counting, simple logic, and social skills through a kaleidoscopic mix of puppetry, animation and short films. In a radical departure for the time, it was designed to deliberately mimic the fast pace and style of TV advertising in order to 'sell' learning to kids: An Aesop-friendly story featuring the recurring characters on the Street would be intercut with rapid-fire 'commercials' for that day's 'sponsors' ("Sesame Street has been brought to you today by the letters A and S, and the number 7...").
"Today's episode of Sesame Street has been brought to you by the letters A and S, and the number 7."
In an homage to Sesame Street, which is sponsored every day by two letters and a number, one episode of The Simpsons was sponsored by one symbol and one number that looks like a letter: “Tonight’s Simpsons episode was brought to you by the symbol umlaut, and the number e. Not the letter e, but the number, whose exponential function is the derivative of itself.”
Have you ever wondered where your backspaced letters go?
When your writing something on the internet and you make a mistake you backspace it, The backspaced letters get transported to a magical trash can that no one can find except for pac-man. Pac-man goes to the trash can when he's hungry and chows down on the backspaced letters you backspaced.
Person 1: Are you addicted to abscesses?
Person 2: Yes.
Person 1: Asexual (+: A catch-all for all other identities and orientations not covered by the specific letters.)
