Even on her appearance on David Letterman not quite two years ago, when he challenged her to serve a ball *through* the front window of I think Ruper Jee's Hello Deli (and she *did!*) and seeing she was as tall as Dave, it didn't *really* strike me just how huge and 'mannish' she is *by contrast* until I saw this:

It's because she's a black *man!* In either case, Bruce is *not* beautiful.
