What is the origin of "cool beans"? I know some sites (wiktionary) claim it's from the Cheech & Chong 1978 movie Up in Smoke, but I'm talking to people who remember it being used earlier. (USA).
I remember using the phrase in the mid-1980s (elementary school in Maryland) , and I assumed it had to do with Jelly Belly (a gourmet jelly bean company).
