Corrected entry: In the scene where Heather says that she invented cigarette paper that burns faster, she humiliates Michele by saying that she didn't invent Post-Its, Art Fry did. The true inventor of Post-Its was Dr. Spence Silver in 1968.

Correction: Art Fry did invent the Post-It Note, Spence Silver merely invented the adhesive on the back.
Since a Post-It Note without the adhesive is just a small piece of paper, Silver deserves the credit.
They're considered co-founders, however Silver accidentally created an adhesive that stuck lightly to surfaces and didn't bond to its surface. Fry had the idea how to use the adhesive and invented Post-it Notes.
