Friend and I drove over to B-Burg while in high school and stopped at the west side location. I knew the girl behind the counter was up to some trick. Lifted up the bun on my burger and lo and behold the lettuce had a rabbit's bite mark in it. At least, I thought it must have been a rabbit. Surely it was a rabbit that had taken a bite out of my lettuce. I was a silly high school kid, and not much less silly today, so I plopped the bun back down and the rest is history. Never said a word.
