A group of former Taco Bell interns claim they came up with the $1 billion idea for a Dorito-shell taco nearly 20 years ago, and they have pictures to prove it, according to Business Insider.
The group came up with the idea as part of a Taco Bell-sponsored contest during the summer of 1995, former intern Andrea Watt told Huffington Post's Jillian Berman.
Taco Bell released a similar product — the Doritos Locos Taco — in 2012. The item is the most successful product in Taco Bell's history.
