Originality is hard

A lesson on how hard it is to be original!

Whilst walking back from town at lunchtime with a colleague, it started to rain. Neither of us had umbrellas, but we on the way back we devised a concept for a double umbrella [which on checking, I see has already been done, of course]. We thought up some names - like Dubrella, Dumbrella... We came up with a rectangular version which we figured could be delightfully naughtily called the Rect-umbrella...!!

A quick look on google and... yup, unbelievably - 'Rect-umbrella' done! For sale in the US - of course.
