Continue Option:
wget has a nice switch '-c'. useful if a site keeps dropping connections on big files. Cool.
Recurse two levels deep:
wget -r -l2 http://example.com
Mirror (and rewrite links to relative):
Use the -k option in conjunction with the mirror option to mirror a website AND have the links all changed to relative.
wget -mk http://www.example.com/
grab a URL w/any dependent files (images): wget -E -H -k -K -p [url]
