Does anyone remember the Watch with Mother Series - Bill & Ben? [I'm thinking of the first black & white series which ran in the 1950/60's, yes, I know, I'm showing my age admitting that!]
For those that don't know it - the characters were string puppets set in a garden behind the potting shed & 'Weed' grew between the two large flower pots in which lived the flower pot men, Bill & Ben. Their language was a bit odd with words sounding like loblob, flobberpop, and weed replied with a long weeeeeeeeeed sound. Each episode ended with the lines "... and I think the little house knew something about it, don't you?
