Goodness of the evietito! If it's speech impediments you're after, then listen no further- Stanley Unwin brings us his aural dyslexia for this classic 'uplode'.
Credit goes to the original ripper for this but Gawd knows who they are. If you don't know the Unwin, I have linked to a youtube vid to give you a taste.
Also while on there, I spotted a brilliant ex-python Eric Idle 'Rutland Weekend Television' clip which is unrelated to this upload, but still gibberish and too funny not to include - I'll just add the link for this one - click here for gibberish
