I think I have a good one..

When I was about 18 or so, I made up many stories for fun. Also did this when clubbing or in bars, and sometimes people didn't fall for it but found them so funny that it kinda worked too :)

So this one time, I met a pretty girl and we were just chatting, when it seemed like she wasn't that clever.. there had been something related to bombing or fake bombing a politician in my country that made headlines and she didn't know the main characters or whatever, so i thought "story time!"

I told her I was with the bomb squad. I was the scout, the first one on the scene, the one that looked in the bag to see if it was a bomb or not. Told her "you probably know the movies, cutting the blue or red line" and said that I am actually colorblind but i have an earpiece to get advice from my caller (I made that name up). I used the color blind trick to prove I was colorblind, and told her some other stuff about how scary and frightening it is to be the first one on the scene..

She found it all super exciting and went home with me because I was such a brave man :)
