Scene: Eating a Caesar Salad in the garden - all home-grown lettuce (we're over-run - see pic!)
Skeptical sidekick: So... [pokes lettuce around plate]... who invented Caesar Salad?
Me: The Romans of course. Caesar, you see?
SS: Did the Romans even have lettuce?
Me: Of course they did! You get Romaine lettuces. And Saint Paul was a Roman wasn't he? He sent Lettuce to the Corinthians.
Comedic responses on the them of lettuce now invited...
