Eeny posted an entry that listed a number of hints to get you through life, but one of them reminded me of a funny true story:

Helpful Hint #1
If you are choking on an ice cube, don't panic.
Simply pour a jug of boiling water down your throat and presto!
The blockage is almost instantly removed.
I had to laugh at hint #1. When Shannon and I first met I told her a story of how I nearly choked to death on an ice cube, but part way through the near death experience it dawned on me that if I just wait a moment the heat of my own body will melt said cube and I'd be fine. And so I was. On the down side, if you have ever done this, you would know about the extreme cold headache that you'll receive that seems to last forever.
