I call this type of shirt the "I'm with Stupid" shirt. That shirt works most of the time because most people are stupid. Only if you were standing next to Stephen Hawking (RIP) would you be clearly wrong. You have an even higher rate of success with a version like this girl's shirt. There's only one Andrew Scott in the world, so chances are good that your shirt is telling the truth. We all know that's the most important thing we think about when putting on a shirt: is this shirt conveying the world accurately.
Hilariously, this girl wore the shirt on the day she met Andrew Scott. It's the one instance where her wish could be granted. It looks like she's embarrassed though, which is understandable because she's basically outing herself as a stalker. Usually it takes a court subpoena for me.
