Isn’t it funny no matter how many times you watch something on DVD you never ever get tired of it if the writing is good enough.
I have the complete series of Porridge on DVD (series 1, 2 & 3 plus the two Christmas specials and the movie) and I have watched each DVD about 20 times each since I have had them.
It is now 2:11am in the morning and I am now watching series 2 whilst I am lazily browsing the internet.
