Oblivion

Alright!!!! *TAKES A DEEP BREATH and hides* XD

I saw a guy wearing a daring do rainbow dash shirt at the Iowa State Fair!

When I first started working in my job, I brought in a Twilight Sparkle cutie-mark mug. I gambled that it would be recognised by fellow bronies (obviously) without being recognisable as a 'pony thing' by non-bronies. Then it came out that I was going to see the MLP movie and my team went and bought me a blind-bag pony to put on my desk, which was very sweet of them (which most people don't even notice - almost a year later, someone actually noticed it and asked if it had always been there. So much for it being a big deal.)

So I'd recommend a similar approach; have something that only a brony would recognise.
