Why do you think manholes are round in shape?

(You need to think a little crooked for this )

(In reply to the practical solution by michael)

but the manhole cover is only the top piece of the manhole itself, which while generally round is not always so. The manhole is actually constructed first, with the road built around it, so the shape doesn't matter (many curb drain covers are rectangular).
