This thread reminded me of a funny story from Seville about ten years ago.
Buddy of mine from OCS was going through a divorce and struggling in primary because of it, so I took him out to try and get him laid and clear his head a bit. I was married at the time so playing the wingman was a fun game for me since I knew I wasn't going home with any of the girls anyway.
So we're in the dueling piano bar and we spot a group of 4 pretty hot girls at a table, so we decide to try our luck. We end up sitting down with them and the conversation inevitably turns to what we do. I'm pretty sure the head hen of the group made some snarky remark along the lines of "you guys aren't military are you?" that led me to believe the truth in this case might not be the best course of action based on our given objective of the evening. So I went with one of several go-to's that I'd heard another buddy (think Barney Stinson type) use on a few occasions; that we were traveling salesmen who sold Snickers with Almonds bars to people with vending machines. The fun part was always acting offended and disgusted when they would ask if you really sold snickers, then you'd play up and emphasize the fact that you sell Snickers with Almonds, like the regular version is beneath you. It's as retarded as it sounds, but you can have some fun with it and it's a pretty good IQ indicator if they actually buy it.
I had a pretty convincing act going that night and you could tell I almost had 3 of them on the hook, but the leader had her best bitchy "you're a lying motherfucker and I'm going to prove it face" on, so I was worried it might have backfired. Just about that time, our other buddy (Barney Stinson guy) who happens to randomly be there that night, comes stumbling up to our table and says hi. Before I could even introduce him to the group, lead girl pipes up, stops me before I can say anything else, and asks our buddy what we do for a living. Keep in mind, he had several go to stories he would use and didn't really favor one more than the others, but without skipping a beat he looks at her and says, "we sell Snickers with Almonds". The look on her face and the timing of the whole thing was priceless.
And my buddy that I was there with went home with one of them that night, so...Mission Accomplished
