No! It's NOT me!

We had a fun Saturday night visiting our friends Mark & Ushy. They've been great friends to me for over 20 years now, so it's always good to see them.
We went into Stoney Stratford for a few drinks & a meal, & I'd intended to take a snap of the house from where it's believed Richard III had the uncrowned Edward V & his brother, Richard, Duke of York, abducted & taken to the Tower of London.
But as we were leaving the restaurant this chap came in. He seemed to have been the victim of a prank, as none of his mates were in fancy dress, but our taxi was waiting, so we rushed out before we thought to ask "Why?!"
