Fast Food Employees, what are some of the most delicious custom ordered items that I could order on my next fast food run?

Yes this post is inspired by this [question] (http://www.reddit.com/r/AskReddit/comments/vhqe7/fast_food_employees_what_is_the_most_bizarre/). For example, the Steak Chulapa from Taco Bell with a Doritos shell on the inside. Or perhaps a McChicken inside the two patties of a McDouble.
