During college, I worked at MSP airport as a baggage handler. Once we had a new guy, and told him the next flight had a number of oversized bags, and we would therefore need a "bin stretcher" (a bin being the name for the baggage compartments in the bottom of the plane). We took it to the next level by letting him know that we didn't own one, so he would need to go to United to borrow theirs. Once he left, we called United, told them the gag, and had them send him onto another airline. An hour and 6 airlines later, he returned, very embarrassed he was unable to complete the task set for him.
