Your strangest or most amusing experience in a fast food establishment?

One of my best friends from high school had worked at McDonalds for a time. One evening when we were both up to no good as usual, he persuaded one of his former co-workers in the drive-thru to give him a headset. Then we sat in the parking lot and told people trying to order that we were out of hamburger meat or if they ordered two number threes we would say "why don't you just get one number six" and stuff like that. When we went inside he gave the headset back to one of the workers and the manager came up there yelling at him to get out and that if he ever came back he was trespassing and blah blah blah. Of course, he's the sort of guy that you can't tell anything so he started yelling back at her. Good times.
