Summary: 

< bug off! >

In response to the question, "Why are manhole covers round?" :  I learned
that it was because the circle is the only two-dimensional shape that has
the same diameter no matter how you turn it.  (The square, for example,
is smaller when viewed from one side than when viewed from a corner, since
a diagonal is longer than a side.)  The implication is that a manhole cover
cannot accidentally fall through the manhole and injure someone below, where
any other shape could.
     There's a second reason?  I'd guess that it would be that since manhole
covers are so heavy, it's easier to roll them than to carry them!

     Do I win?
