It just poped up on my mind about this when i started having hick-ups on me this morning. I was thinking.. what are the solutions to cure hick-ups?

I have compile a few solutions:

1. Drink water
2. Sip water 8 times.
3. frighten the person who is having hick-ups
4. Hold your breath as long as you can.

What are the other solutions? why do we follow this solutions?
keeps.. wondering...
