How do I get airplane attendants to give me 1st class stuff?

It's nothing big really. I just want an amenity pack that goes out to 1st and business class when I'm in coach. I'm going on a boeing 777 from Dallas to london and London to UAE and the amenity packs have blindfolds and toothbrushes and chapstick. So it's necessary stuff really. Do I just ask them? And I also want to use these noise cancelling headphones for 1 St class also. Any tips? I'm traveling American airlines.
