When his wife Val inquired what he was doing, he replied: “I want to water the plants.”
Seemingly intending to humour him, she simply replied: “Really? OK. Give them plenty.”
As Ralf returned back to sitting position, his wife then asked whether the plants were doing OK now.
To which he snapped: “Yeah, fine…why are you looking at me like I have two heads?
“You never give the plants water.”
Val then pointed out: “No, because they’re plastic.”
