This bit of Wikipedia
pisses off one of my colleagues who teaches the Gen Rel class at my university as before said Wikipedia page it was a good question to set.
He will, no doubt, breath a sigh of relief at it being an urban legend. If it's physicsmyths.org.uk that's the source of this, I'm going to have to go and roll up a big one or bake some brownies to continue. I wonder if the board software supports LaTeX?

And what are the holes that there are "a dizzying number of", anyway?
