The Comics Curmudgeon has some hilarious shirts utilizing slogans snarked from comic strips.
This page explains them all. Of course FBOFW has a couple (Roadside! Boxcar!), but my favorite is from Judge Parker, which I don't even really read, in which a guy brags about a full boat-wrestling scholarship.
I've read the strip that started it all (scroll past the pathetic Family Circus to read it), and the only way I can even force it to make sense is if it was a typo for "full-bore wrestling scholarship," maybe? But what kid says "full-bore," and how can the strip go through inking and editing and "bore" turn into "boat"? Oh, I don't know. Maybe wrestling boats is really good for you, like running the stadium steps at crew practice.
