mpion: the MP3 player that fights acne

Sure, the world has seen it’s share of goofy MP3 players,
but this one really takes the cake. The saying goes “There’s a sucker
born every minute…”, but they should have added, “…And some will rub an
MP3 player on their face like a Norelco razor”.
The mpion actually claims to fight acne by releasing positively and
negatively charged ions, which supposedly neutralize breakouts. It will
cost you $184 and only holds 128 megabytes of music, so I’m thinking
this is a last resort for the seriously desperate, angst ridden type,
who has a terminal case of crater-face. Keep rubbing my friend. Who
says wishes can’t come true, if you just believe. I can’t figure out
why a young and thin Rosanne Barr is pictured using this.
