Found this on the net while hunting for other info, gave me a damn good laugh:
Q: I forgot to close the valve in the bottom of my primary fermentor. I poured my beer into it and now all the beer is on the kitchen floor. Is my beer ruined?
A: Yes. There is no way to get it back in the bucket. In addition, your wife is going to be very angry. The best thing you can do is mop the floor, then go and purchase wine and flowers for your wife. Then you will need to mop the floor again because it is still sticky.
Q: My brewpot boiled over on my wife's new stove. Is my beer ruined?
A: No. Your beer will probably be fine. You're just going to have a little less of it than you expected. You also have a very nasty job ahead of you. Burned on wort is very difficult to remove from your stove and brewpot. It is probably best for you to spray a cleaner like 409 on the stove and let it soak while you go and purchase chocolates for your wife. You will need a very large box of chocolates to keep your wife occupied while you scrub the black crud off the stove.
Q: I did both of these things on the same brew day. What do I do now?
A: Purchase diamonds for your wife in addition to the items above.
