April Fool's Day.

[Guilmon and a shotgun]

Google had a variety of speeds it measured your searches in, including:
2.0 shakes of a lambs tail
8.56 Hertz
1.21 Gigawatts
0.03 nanocenturies/microfortnights
they also had an animal translator downloadable from the uk page

Also, Ben and Jerry's website had lickable icecream on your screen and Kodak announced sniffable photographs.

ah, the laughs we had in that IT lesson...
