Hey, it's not a season 5 episode!
But seriously. I don't think that the writers were intending to convey what they did, unlike in Uh-Oh Canada where I genuinely couldn't decide whether they could or not. But the mistake is there and it gets really uncomfortable. On a personal note it really does bug the living crap out of me that they're glorifying something as bad for your health as tanning. Yes, they have the line at the end, but it... just bugs me.
