If you dial the number that pops up on the DHL Express computer, 1-800-I-AM-HELP, listed here under Tech Support, you will get a porn hotline. I tried the free call, and got several seconds into it...
The question he asks: What does the number really spell? 1-800-426-4357. Assuming the porn place is savvy enough for acronyms. I got to GANG FLP or HANGELS, which are unsatisfactory.
