You guys are terrible at not watching trailers. Just get a decent pair of in ear headphones and listen to a podcast for a while. Nobody can hear them so you're not disturbing anyone and you really don't have to blast them either. Just loud enough that you can focus on the podcast and you won't hear anything from the trailers except explosions and the parts where they go BWAAA.
It's pretty easy to tell when trailers are ending even if you're not looking at the screen and every theater I've ever been to has an ad for concessions between the trailers and the movie so you have plenty of time to put the headphones away.
Fingers in your ears and humming, sheesh.
PS if you're going to see The Mummy maybe just leave the headphones in.
