I have the wrong sort of face

I caught up with an old friend to go to a comedy podcast recording of @TonsilHockey with Olga Koch and Catherine Bohart. It was lovely to see my friend again, and the show, which was a watch-a-long for an episode of Heated Rivalry was a lot of fun.  There’s something great about being in a room full of people who are locked into the same thing, whether that’s a tv show, a theatre production, comedy show, gig, or even (I imagine, though I have no direct experience of this) for sport. The shared highs and lows, laughter, cheers and groans are so much more fun when shared, and it’s a good reminder of what pack animals we still are any time we get an opportunity.   Anyway, I laughed a lot, with Phil Wang as the novice tribute being inducted into the cult, having not seen the show, with the rest of the room the experts on every scene. 

So far so good... but I'd like to know what is it about me that means I am the person that always gets picked on to talk?  Particularly if I am in a comedy audience... do I look that much out of place?  I'd like it to be because I look friendly and fun but I'm not convinced that is the case.  In fact, as soon as someone puts me on the spot, particularly where a microphone is involved, I get stage fright and disassociate, so I have absolutely no idea what I am saying ... luckily that hasn't got me arrested or kicked out of anywhere so far so I'm taking that as a result.  The real kicker here though was that I was used as a callback later on, putting me on the spot for a second time just as I had relaxed.  Maybe I should wear a hat saying 'Leave me alone'?  I suppose it serves me right for being more interested in chatting to my friend rather than doing my usual thing of making sure I was out of the eyeline of the hosts - lesson learnt.   Anyway, I survived that, but then at Waterloo station got stopped 3 times by tourists asking for directions - that was a lot more welcome, and there were no microphones involved, but what is it about my face that makes me a target?
