Of all the possible fake text messages that the creators of this Palm ad could have come up with, somehow they agreed upon: "Jen, it's 80's night. You won't even have to change!"
It will probably not surprise you that I spent way too long thinking about the possible implications of this weird, weird message. (You can click on the ad to make it larger.)
1) The sender (let's call her Catty Carmen) is being friendly. Maybe Catty Carmen and Jen spent the day together at a hippie arts festival or just finished a performance of a 80's-themed play. For whatever reasons, Jen is dressed like this. Carmen finds out that the ragin' party that night is all about the Eighties, so she quickly texts Jen to let her know that she needn't change -- she's just looking out for her gurl!
2) Catty Carmen is a bitch. Jen and Carmen used to be friends, but now they are enemies. Maybe Jen stole Carmen's apple-flavored lip gloss and never gave it back or Jen spread wild rumors about Carmen's fling with the Russian exchange student. We're talking Lauren-Heidi proportions here. Carmen saw Jen in the dining hall and totally made fun of her lame, try-hard outfit in front of everybody. And just because she's evil, Carmen sent Jen this text message to add insult to injury.
3) Catty Carmen is a liar. There is no 80's party. She just wants Jen to show up looking like a fool.
