You were in some form of social situation, be it a party, a pub/club or just round at a friends house and they wanted to introduce you to someone. This someone turns out to be 'Moshy' from the national express ad on the side. How do you react? Do you acknowledge the fact that you've seen him make an utter arse of himself across the interweb, or do you bite your tongue and spent the whole time trying to keep a straigh face and avoid eye contact?
What would YOU do?
