(as) round as Giotto's O

Quickly yet perfectly done. The phrase refers to the Italian artist Giotto, who is said to have promptly drawn a perfect circle to demonstrate his artistic abilities for Pope Boniface VIII. Wow, I can't believe you wrote this paper in one night—your writing is round as Giotto's O.
