One of the most brilliant spinoffs was a 9 episode series done by Michael Palin after python ceased in the late 1970's, called Ripping Yarns.
All the stories were different and unrelated, but all done in the Boys Own style of boys comic of the 1930's and 40's.
My favorite two of the nine are
the pilot episode , 'Tomkinsons Schooldays'
Favorite line ' I was nine miles from Graybridge when i was caught by the School Leopard'
and a bit of dialogue between Tomkinson and and teacher in the Model Club after school:
"Whats that, Tomkinson?"
"Its a model Ice breaker, Sir"
" Its a bit big for a model isnt it"?
"Yes sir, its fill size Sir, its got three engines and.."
"Well if its full size its not a model, is it, boy"
"No Sir"
"There will be a hell of a stink if this comes out a Speech Day Exhbition, but i wont say anything if you can get it down to a maximum of say..100 feet by tonight"
And my other favorite is 'Golden Gorden', a tale of footbal in a northern town in 1932.
