Lies lies and more lies.
The best ones are those which are true, you don't have to remember too much then.
Anyway, if you do it too many times, your tongue can often split, and all the little doggies, will have a little bit.
That or your pants will catch fire.
Personally, I advise caution due to the inconvenience you are likely to experience in any of the above situations.
