George and Lynne are in the garden. George pricks himself on a thorn, says 'ouch' and asks Lynne why roses have thorns. Lynne says that she is just pleased that thorns have roses.
The time has come and George is finally sorting out the garden. He got a taste for tidying things up after the cleaning incident yesterday and has decided enough is enough with the overgrown garden. Unfortunately, his idea of tidying up the garden is to cut all the roses down.
After George cuts his finger he asks why roses have thorns. His question is rhetorical but the answer is that they have grown them over the centuries and millennia to protect their sweet tasting petals from herbivore predators.
Lynne doesn't know this but attempts to come up with a witty answer. It does not make sense and doesn't George know it. Look at his face! He has literally never heard anything so stupid in all his life. All he wanted was a plaster and all he got was nonsense. It's a good job he's not a haemophiliac.
