In the 30 Rock episode "Goodbye, My Friend", TGS cast members begin to sing the song following an announcement about the royalty fee for singing "Happy Birthday to You" on a television show. The cast is interrupted after the first line by a character entering the scene. In the Community episode "Mixology Certification", a scene starts with the last two words of the song ("... to you"), implying it had been sung in its entirety, before Pierce confusedly asks, "How come we only sang the last two words?"
The printables I was adding to my store at that time were very inexpensive - I charged $3 at most. Throughout the month, I'd make a sale here and there. My phone had the Etsy Seller app downloaded onto it and the app would notify me of a sale by making an AMAZING "cha-ching!!" sound. I loved it even though I only made enough to pay for my fancy lattes here and there.
