Ryan North, author of Dinosaur Comics, likes a lexical relation. I don't want to steal his comics, so forgive the links-only approach. I'll do a little summary:
- T-Rex finds his opposite: "when I'm taking a beautiful woman out to dinner, he's helping a homely man throw up!"
- T-Rex plans to find a way to say 'yes' and 'no' at the same time.
- "The opposite of digging a ditch"
- (my favourite) T-Rex on homographic homophonic autantonyms. Because language is awesome.
