Specsavers is a British retail chain that sells glasses, contact lenses and such. Their new commercial features John Cleese as Basil Fawlty…though I'm not sure how we're supposed to know it's Basil Fawlty, as opposed to just John Cleese being a big jerk…
[UPDATE, EIGHT MINUTES LATER: Six people so far have written to me to point out that they play the Fawlty Towers theme and that Fawlty did the branch-thrashing bit in the series. Guess my mind was elsewhere and that it's been too long since I saw the show.]
