"Alcohol loosens your tongue and makes you act, say and behave in a way that's not you." – Mel Gibson.
I would like to state that this is a load of twaddle. Alcohol simply removes inhibitions. In other words, alcohol lets you do stuff that you normally wouldn't do for fear of social or moral reprisal (i.e. guilt), but it's STILL YOU.
I'm not defending Gibson, and I'm not defending the use of alcohol – I've stopped drinking, for all intents and purposes (I now have a glass of wine once a month or so) – but from personal and observational experience, if you want to know what people are really like, get them drunk.
Mel Gibson, the anti-Semite Catholic bible-bashing Jesus-loving American-Australian-American actor is a good actor, but that's what he is: an actor. I don't believe him as far as I can throw him. Unless he's drunk.
