Jack Black's hangover cure

While researching hangover cures for the good of humanity over the Christmas I came across one very interesting idea.

Lettuce.

Yep, Jack Black reckons it soaks up all the "alcoholical particals" in your system, thus cleansing it completely.

What a wacky guy! Hoho etc.

Anyway Jack, this defies the purpose of a hangover cure. I mean, we all know that any food consumed while in the throes of a hangover contains no calories whatsoever. And lettuce seems a bit... healthy. I think I might just stick to my rasher sandwich on batch bread.
