There's a 21-year-old guy named Jevh Maravilla who's a student at the University of Houston.  And back in July, he and his friend Christian were eating at McDonald's when they noticed a blank wall.

They also noticed that there were a ton of other posters on the wall of people eating McDonald's, but none featured Asians like them.  So they made their own poster, photoshopped it to look like the other McDonald's ads on the walls, and had it printed.

Then Jevh got a McDonald's employee shirt from a thrift store and wore it into the store to hang up the poster.  And he made a video showing the whole mission.
