Didn't sit on as ruler, but you all know those wicker trunks that you can use like a coffere table? Had one of those years ago, had a 1/4 piece of glass cut to fit on top, heavy glass. Well, dumb me backed up to it and sat down.Yep!! Darn thing broke right in half! I didn't realize the trunk lid didn't have flat even, supported base. But then, I always seem to to dumb things like that, so I'm use to it!!
