<human>: Can you give me a shortened version of the text?

My girlfriend and I (dating for 3 months) were hooked into a double date with a guy, who used to (maybe still does) have a crush on my girlfriend, and his girlfriend in NYC in a couple weeks. 

The reason we want to show the other couple up is because we both agree the guy is an asshole for hitting on my girlfriend while he was with his girlfriend. Also he constantly sends pictures of him and his girlfriend to her on a regular basis. We don't want to ruin their relationship, we just want to intimidate them as a couple.

Our date will be in Manhattan, around Times Square specifically, so we'll be limiting the agenda to only that area. So what I'm asking basically is; what should we do and/or where should we go on the double date to assert dominance over the asshole and his girlfriend?
