Also, as far as I can remember the larger the mass, the more it strains the fabric of space/time (not to mention the fabric of the shirt if the object happens to be a large bust). The strain of space/time is such that light warps around it and time can essentially slow down (which would explain why sightings of large busts seem to last an enternity, but still never seem long enough).
Sorry, I'm too geeky for my own good. -_-
