I had an interesting conversation with some friends about puns. After riding a bike for the first time in a long time, my friend David said it was “good to be back in the saddle,” and he wondered whether this counted as a pun.
Since a bicycle actually has a saddle (the more technical term for the seat), it could be argued that this is just a literal statement. On the other hand, “back in the saddle” also has a metaphoric meaning, so it could be argued that his statement has two simultaneous meanings, and therefore should indeed count as a pun.
It then occurred to me that this is an example of a class of statement whose literal and metaphorical meanings coincide — a metaphor for itself. You might say it is “autophorical”.
Here are some other autophorical statements. Perhaps you can think of more:
“Sorry, the train derailment threw me off track.”
“Hey, everybody on this cruise is in the same boat.”
“Drosophila were dropping like flies.”
“The entire soccer team is having a field day.”
“I went out on a limb to rescue your cat from that tree.”
“The editor cut my novel to five pages, to make a long story short.”
