To those who don't know what to do with the Shorty McForty...
...take the grip off your 5D (or, better, the 6D!) and put on a wrist strap, put it in green square mode, turn on live view, and now, as far as non-photographers are concerned, all you've got is a slightly oversized P&S camera. Hand it around the table at the party and nobody will think twice. As a wedding photographer, get in the conga line with the rest of the guests taking snapshots. Use it on the street.
You've got something that, even at second glance, to most people, just looks like a high-end P&S camera. And not a one of them will realize that it's really the reigning IQ / low light monster it actually is.
And, yes -- the optics in the lens are right up there with any L zoom, including the latest ones.
And, if nothing else? It makes a perfectly serviceable body cap....
