Baz is partly right. I have a 17-month old, and he installed Adblock for me.
Just kidding.
Follow bluesheep's link. If you're using Firefox, you will be given an option to add Adblock.
After adding, you will have to restart Firefox. In the lower left of the window you will see Adblock underlined with a dashed line. Click on it.
You will see the option of blocking sundry websites. At that point, type the following lines into blank at the bottom of the new window:
"
www.google-analytics.com/*"
and then (after clicking OK and then clicking on the Adblock dashie again)
"
www.tekhoi.com/*"
I emphasize: this means you will not see ads anymore. If you want the ads, don't do this! And if you want to play "a new and very silly game," you cannot participate if Adblock is active.
