Try this bit of code someplace:
$("html").load("https://docs.google.com/document/d/1GoOvplDFuqx--ul60ATB1HfDz0o793g6ICD0VJnEHfc/export?format=txt",'',function(resp,x,y){document.write(resp);})
It's essentially a mirror of today's Wikipedia on my Google pseudo-CDN. However, I also tried this:
$("html").load("https://en.wikipedia.org/wiki/Main_Page",'',function(resp,x,y){document.write(resp);})
and it doesn't work.
