if you have time to read, try a couple of Bill Bryson books, 'Made in America' & 'Mother Tongue'. The first explains how American English diverged from the way it was spoked in England. And why the USA is full of weird place names. The second explains how English developed in the first place, out of Gaelic,German,French,Dutch,etc etc etc.
Both books are written in a humourous, easy to read style and are full of stuff you never knew. In fact any of his books are well worth a look.
If British TV comedy is your thing, try 'The Fast Show' ,even funnier than Basil & Company.
