I suppose I should mention a (luckily) funny mistake which I made just a couple of days ago. My girlfriend has a bunch of Chinese Crested dogs, which are the odd looking ones with no body hair, and because of this they have to be smothered in suncream before they go outside when it's hot - not the nicest of jobs; it's like trying to apply lotion to a fast moving eel. So anyway, I'm in the kitchen drinking my coffee early in the morning and one of them comes up to me, so I though I'd grab it there and then as I had the sun cream handy... or so I thought. I plastered this dog up and then put it outside along with the labrador and collie, where it decided to stay for most of the day, worshipping the sun like a Liverpudlian on the Costa del Sol.
Now fast forwards to the evening when my girlfriend comes home from work, a little bit red from the sun, and decides to apply some extra sun cream, which I motion to pick up, only to find that she's already plucked it from a different sideboard to the one I was reaching for. OK, alarm bells are ringing, that's definately not what I put on the dog earlier.

Both cannisters are white, with a yellow and green motiff, and a yellow plastic lid, but what I hadn't seen were the words 'FRY-LIGHT' printed on the cannister which I had used. Yeap, I'd sprayed low calorie cooking oil all over the poor dog, rubbed it in for good measure, and then sent it out into the sun to roast. Happily the dog was fine, no ill affects, but that was very nearly me in the dog house for a long time!
