Which U.K. TV character called electricity "elec-trickery" and the telephone the "telling bone"?

“Catweazle” was a British fantasy television series, starring Geoffrey Bayldon in the title role, and created by Richard Carpenter for London Weekend Television. The 1st series, produced and directed by Quentin Lawrence, was screened in the U.K. in 1970. The 2nd series, directed by David Reid and David Lane, was shown in 1971. Each series had 13 episodes, all but 2 written by Carpenter, who also published 2 books based on the scripts.

The series featured Geoffrey Bayldon as the title role, an eccentric 11th-century wizard who accidentally (by total immersion in water) travels through time. In the 1st series he arrives in the year 1969 and befriends a young red-headed boy, Edward Bennet, nicknamed "Carrot" (Robin Davies), who spends most of the rest of the series attempting to hide "Catweazle" from his father (played by Bud Tingwell) and the farmhand Sam (played by Neil McCarthy). "Catweazle" searches for a way to return to his own time while hiding out in a disused water tower, which he calls Castle Saburac, with his toad called "Touchwood".

Catweazle mistakes all modern technology for powerful magic (Arthur C. Clarke's 3rd law - any sufficiently advanced technology is indistinguishable from magic), particularly "elec-trickery" (electricity) and the "telling bone" (telephone).

The series won the Writers' Guild of Great Britain award for Best Children's TV Drama Script in 1971. On March 29, 2010 the series was re-released in the U.K. to mark its 40th anniversary.
