Everyone looks like they are doing something different.

Data: put some headphones on him and he is A DJ dishing out some sick mixes.

Riker: looks like he took too much

Picard: having a seizure

Worf: looking down from a balcony at the club choosing which of the Duras sisters he is going to put the moves on.

Dude on the left: just saw something scary and is battling his fight or flight reflex.
