1. Look at your watch.
2. Say, "Oh shit, they're firing up the LHC in a few seconds; we have to check it out because this is their biggest collision ever and they have a live webcam IN the collider."
3. Rush to the computer and go here. While it's loading say, "Hope we're not late. It's starting literally any second."
4. Take the joke as far as you want. It can be a great way to get someone to admit a secret they never wanted to tell you until they were about to die.
