Yesterday’s Dinosaur Comics:
T. Rex maintains he just wants to warn people about doors hitting them — this strikes me as dubious indeed — so he has to rephrase an expression that has been lexicalized as “sassy/sarcastic” (conveying ‘Get out of here!’ or something of the sort) by one that has only the literal meaning he intends. Similarly for “What do you want me to do about it?” (conveying unwillingness to do anything about it) and “Welcome to the real world!” (conveying that things are generally tough in life, so you should stop complaining). Not a fully successful strategy.
On Facebook, Jeff Runner took great pleasure in the strip, noting that he especially liked “the part about words being filed under “sassy molassy” in the lexicon!”
