What if I have a shirt that says “From the river” and my friend has a shirt that says “To the sea?”

Would we be arrested for standing too close to each other?

What if we stood the wrong way round, and our shirts read “To the sea from the river?” Would that be an offense?

What if the shirt was in the form of a rebus, with pictures and/or wordplay as stand-ins for words like “river” and “sea?”

What if it were a remix that nevertheless put the original slogan in your head: “River. Sea. Some assembly required?”
