This would give me time to eat my dinner, pop out to the pub for some swift ones, and still have time for a good long No 2 and know that I have missed nothing on the goggle box and can then settle down to watch "Zulu" or "Mary Poppins" etc. I've lost count of all the endings of good films because I have been summond to the table for Xmas dinner, or popped out for a pint, or had to rush a No 2 in the advertisement break.
