Taboo (aka The Elevator)

What happens when two people are trapped in the enclosed space for an extended period of time? Hmmm...

'Taboo' is based on a story prompt that was given to me by a friend. It should involve the use of two items from the following list:
1) A single pudding cup
2) An iPod
3) A marker (but no paper on hand...)
4)A single can of soda
5) A paperback novel

In addition, those trapped in the elevator should arouse the suspicion of a passer-by once, or if, they ever manage to get out of 'The Elevator'.
