Betty Behind the Ears

Here's the awesome and super Ms Boop
Who would often say "Boop-Oop-A-Doop"
As a dog she debuted
Quite a slog for her dude
Who, by law had to scoop up her poop.

Betty Boop began life as a cartoon dog, an anthropomorphic French poodle with floppy ears, ears which over time evolved into hoop earrings as Betty became fully human. Image: Betty with Bimbo, who remained a dog, in Bimbo's Initiation (Dave Fleischer; 1931).
