"Choppin' Broccoli" or "The Lady I Know" is a song written by Dana Carvey as songwriter Derek Stevens on Saturday Night Live. The skit goes that songwriter Derek Stevens doesn't have a demo tape at a meeting with producers, so he tells them he wanted to play it live. He then sits at the piano and makes up a ridiculous song about a woman he knows (the song is entitled "The Lady I Know" but SNL fans have come to know it as "Choppin' Broccoli") going to a food store and buying broccoli then going home and chopping it. Look it up on YouTube, I guarantee you'll laugh. It's hailed as one of the funniest SNL skits of all time.
A hardo is a person who tries extremely hard at everything. Most times a hardo will try very hard at things that do not require excessive effort. For example, sports practices, gym class, etc.
Wow did you see Jack at practice today? What a hardo!
