(Strip Number 1368, Original Publication Date, 17 November 1988)
Panel 1: The next day, we see Lawrence question Mike's enthusiasm for the thesaurus by questioning its use.
Panel 2: Mike proposes the application of calling Brad Luggsworth a dork to his face and getting away with it because there's no way HE would know what Mike was saying.
Panel 3: He then asks Brad what it's like to be inept, fatuous and inane. This is because like his creator, he does not know what the word 'dork' is a synonym for and thus does not call Brad a lout or churl.
Panel 4: We next see Mike protruding from a snow drift because Brad took violent exception to having that snotty jerk Patterson think he can get away with calling him a clumsy oaf by dressing it up with ten-dollar words. Frienemy Lawrence surmises that maybe Brad took exception to his tone of voice.
Summary: The reason for the header line is that stupid segment in Brad's Liography that has him kick the crap out of snotty rich kid Mike in the name of poor kids like himself. The reason for Mike's getting pasted is his breezy assumption that Brad can't possibly know big words he himself didn't because he's an athlete.
