Good idea: putting your new betta fish's (named Bamboo Blue) bowl on a high shelf sothat your dog that loves to jump, jump, jump can't reach to knock him over.
Gettinga hamster(they're EVIL i say, EVIL:grumpy::grumpy::grumpy:! i they look cute, but, come on, who'd want a hamster if you can have a bunny:biggrin2
Bad idea: taking a nap during the day when you should have been cleaning the house and now you'll be cleaning until the overnight and the nap you took is basically null and void because you're still going to be absolutely exhausted come tomorrow.
Bad idea: stuffing the resulting crap into an unused closet, forcing the door shut, forgetting about it and... being buried in said crap several months later.
