Well I had one today. I found it very funny to be honest.
First set the scene, I'm alone in the entire store (I work in retail, oh the joy) getting thing's set up before all the other staff come in. So I think I know I will stick some MLP music on my Ipod to cheer me up. So working away I find myself starting to sing along minding my own business, but I don't care because I'm all alone in the store... Or am I? Nope, turns out while I'm mid verse of Art of the Dress the morning shift had arrived and about 4 people where staring at me wondering what the hell I'm doing, singing a song about making dress for someone called Twilight, Applejack, Rarity, Fluttershy and Rainbow Dash. I quickly changed the subject but got a few people asking what the heck it was all about. So I told them, even one guy said he will look the show up. So I may have converted my first person to the love of the pony. Now I get called "The Bronie" by people at work... Great

So anything like that from anyone else, or just me?
