brain teaser

there's this cell phone ad at my subway stop which really makes me stop and ponder it every time i see it. darkpony and i have even discussed it! the ad shows a text message on a phone that says, "jen, it's 80s night. you won't even have to change." i find this text message to be a bit ambiguous, and i have come to the following two conclusions as to the meaning of said text message:

1. jen is already at an 80s themed party, so she's dressed perfectly for an 80s night out at the club.
2. jen's friend is a total bitch who thinks jen always dresses like she's stuck in the 1980s, and this text message is a dig at jen's wardrobe.

i'm going with #2.
