Fun article about Ms. Pac-Man.

Here's a couple more to make it a nice, square number.

8. Once her initial leggy incarnation as Crazy Otto had been shelved, Ms. Pac-Man went through a baffling array of name changes: Pac-Woman was eventually vetoed by female employees of Midway, and revised to Miss Pac-Man -- until someone noticed that animated inter-scene depictions of the male and female Pac-Men getting together and producing a child now illustrated a bastard birth out of wedlock. From there, it shuffled to Mrs. Pac-Man and, at the last minute (within 72 hours of the production line startup of the original coin-ops) finalised as Ms. Pac-Man.

9. The arcade game Ms. Pac-Man was not created or authorized by Namco, who holds the original license. The idea behind this game was to make an upgrade for Pac-Man called "Crazy Otto", developed by General Computer Corporation (GCC). GCC approached Midway Manufacturing about buying the upgrade, which Midway did. Midway (Namco's American distributor) then altered Crazy Otto to make Ms. Pac-Man.
