The different portal pages listed are pretty funny, but the €œAnswer to Life€ one really gave me a good laugh. I guess these are more like tricks than tips, but they are still fun and gave me something cool to mail to my tech buddies.
Another cool thing I found in the Blog was this trick. (It's not Google related but is still pretty funny. Just so you know it's LONG so make sure you have time to watch if you check it out):
01. Go to START, RUN, then type CMD
02. Then type TELNET, and press Enter
03. Then the letter €œO€, and press Enter
04. then type towel.blinkenlights.nl enter
