I actually hope it was, if not this would be even more ludicrous... but, most letter openers I've seen aren't much sharper than butter-knifes

Same in the UK, quite a few spam calls... odly a few that call an say nothing too - literal silence - then hang up

Found a few flees in the carpet last months ago, cleaned up, hoovered etc... then haven't seen any more since. A good clean, flee comb an a few sticky catcher-thingies should do the job fine.

I could see the slugs already existing as a waste disposal solution and the dots just 'redirecting' them too...
