Nope the 737 was and is not known as the guppy

I remember calling the 737 either FLUF or Fat Albert.

Hate to disagree, but back in the 80's when I worked for People Express and later, Continental the 747's were whales and the 737's were guppies.

The stylized stickers on the cases that the pilots carried their charts in even had those nicknames on them. It was a Boeing thing, whale vs. guppy, having nothing to do with the actual transport aircraft known as the guppy.
