Yesterday's Monday's conundrum

Note to self: put in the right date when you schedule a post.

Go back for a look if you missed it. OK many will have heard it before, but the only comment I got was in meatspace (and not by the usual guy). So there's a quality pint of TT's Landlord paid on next time he's in the local!

The name for the object in question derives from the Latin for shadow - umbra. It's a brolly.
