Dont forget that to sound truly authentic, you have to slightly alter your word order.
"That's really annoying." becomes, "Really annoying, that is."
Also, all vowels are lengthened, and all consonants are slurred:
"Hey, watch where you're going!" translates to, "Ai, wosh weh yeh're goen!"
The word "luv" is used omnipresently (especially when speaking to a female):
e.g. "Ta, luv!" "What's the matter John luv, blue meanies?"
Note: Although it sounds essentially Beatlish, it is not always politically correct nowadays!
Try speaking it out loud, it doesn't sound half as weird as it looks!
