This somehow reminds me of an asterix comic (and film) I once read (and saw).

Not that this helps your tuner situation, but the film is called The Twelve Tasks Of Asterix, and, although IMDB doesn't say so, the English dub had Bill Oddie as Asterix and Bernard Bresslaw as Obelix, IMO much better than the Craig Charles/Howard Lew Lewis combo that they used for Asterix In America.

The good thing about seeing Asterix films at the cinema is that you needn't worry about tall people sitting in front of you, as the rest of the audience is under 10...
