I just saw this on Digg....

It was my birthday, people were searching for a gift for me... ^^

Woah-- here's another interesting spike around the same time... google.com/trends?q=blowjob%2C ...

i would really like to know what is behind this...

and another... google.com/trends?q=foot+sex
and another... google.com/trends?q=fetish+sex

now i'm REALLY curious....

Perhaps on that date Google Trends started using the full search logs rather than the "safe search" logs.

Though only one of the two adult-ish phrases peaked, Roger... if you're right then perhaps one is more safe than the other.

Exactly. The blue phrase is not unambiguously adult-ish.
