lol..when I bored I just watch TV or playing games..instead of searching "Thank you for your purchase"..haha.. but nice "trick"..lol
If you some more results, try "thank you for your purchase" in alexa instead of google..........you may find a tresure of info products..
Here's a fun boredom-buster : Try google-ing up names of long lost friends (or former boyfriends?) to see if they're now famous (or in jail) (or worse than jail, now in politics lol ) ?
