The most often shown "best of" is the first Monty Python film "And Now For Something Completely Different". It was made for cinematic release in the US as an introduction to Monty Python, and features a collection of remakes of some of the Python's best known sketches including the Dead Parrot sketch.
There is also "Parrot Sketch Not Included", originally shown on UK television on 12 November 1989 for the 20th anniversary of Monty Python, and featuring Steve Martin introducing the ultimate collection of Python classics squeezed into 72 minutes including The Ministry of Silly Walks, Spam, The Lumberjack Song along with some lesser-known delights (e.g. the Queen Victoria Handicap race). All except the Dead Parrot sketch (hence the title). It also features Graham Chapman's very last appearence with the Pythons befor his untimely death (when they are briefly glimpsed in the cupboard at the end). He died of cancer shortly after that was filmed.
Hope this helps
