Just in case proof were needed to show that Google's technical staff are, indeed, totally insane, here's an advanced search with the language preferences to 1337 speak (i.e. the incomprehinsible alphabet used by those who consider themselves to be wonderful 'hackers' - and also tend to use the word 'uber' a lot).
For the uninitiated, this basically involves butchering the English language by using '3' for 'e', '7' for 't', '1' for 'l' and so on. Managing to convey the impression of 'gangsta-speak' is (apparently) considered a bonus. For example:
"PH1ND P4G3Z 7H4T L1NK 70 d4 P4G3"
or alternatively . . .
"Find pages that link to da page"
