This is crazy but it might work: 1. Start talking about a prize you won, something like "Remember that radio show I called? Well, finally I won the macbook pro contest". 2. Set up an environment where you have to go somewhere but you simply can't so your friend needs to ask a favor to show up at "blablabla" and show "this code" in the name of "Blablabla". Another friend of yours should say "ok, I'll go". 3. Talk about when they are at the "public place" the day X from 10 to 12", your friend talk about he won't be able to arrive earlier than "11:30". Give all the details like "I have already talked to them, and I have told them that my friend is going to pass by to get the iPad and that they only need to show the code in his mobile. Anyway, they are going to be there from 10 to publicite whatever...". Just wait from 10 to 12 that day at that place, bonus points if you print some "radio t-shirts" or something...
