For reasons I won't bother you with, I had occasion this week to search for the presumably meaningless word 'mnmn' on Google. The search yielded 3,370,000 results. This will presumably increase to 3,370,001, once Google indexes the page you are reading now.
Intrigued, I dug around some more. There are 159,000 images of 'mnmn' (some of them rather rude), and 3,370 videos, including this one of the Muppets' legendary Mahna Mahna song (presumably a typo), with its soundtrack removed for copyright infringement reasons:
It's time to face reality, my friends: I appreciate the irony of this coming from me of all people, but there is simply too much crap on the Internet.
