I was reading the latest thread about about Pineapple on Pizza, which included some comments about sweet corn on pizza. @MrDibble commented that in his country “sweetcorn” usually meant canned creamed corn, and the non-creamed variety was called “kernel corn.”
Oh. Well that explains that officer’s name in Catch-22. (I’ve still no idea if there’s a deeper meaning to “Colonel Cathcart”.)
