“I was a vegetarian until I started leaning toward the sunlight”

“I was a vegetarian until I started leaning toward the sunlight” said comedian Rita Rudner, who was probably exaggerating her vegetarianism. The one-line saying has been published on many websites and has been part of Rudner’s comedy act since at least the early 1990s.
