Stephen Fry and his panel discuss how you can use a rhubarb stick to clean copper, a discussion ensues regarding Fry's kettle. Taken from QI D episode 12 - Domesticity
@Menegoth "no wonder f-ing Twinings had you pal..." referring to the fact that Fry was the protagonist in a few Twinings commercials (rather funny ones at that, you can find them here on RU-vid as well)
"If i walked into a room and saw a man rubbing rhubarb on my silver..." Well he'd better have brought his own then 'cause you never rub another man's rhubarb :D
One time when he appeared on Qi, Rich Hall randomly asserted that rhubarb is made of meat. IAmEki is clearly a ninja for recalling this throw-away line. If you don't know Rich Hall is a hilarious US comedian. Check out his song 'George Foreman Grill'. P.S. It's currently late at night and I, like many people, am stuck on a Qi loop.
