Also apparently one attoparsec per microfortnight is about one inch per second. So next time a cop pulls you over and says "Do you know how fast you were going?" you can reply with, "Ya I think I was going about one attoparsec per fortnight... is that a problem?" I'm sure they'll let you off.
On a completely unrelated note when coming back from lunch the other day I found this totally non-descript CD-R lying in the grass. It was all dirty and soaking wet but I thought we could salvage it. After scrubbing it and letting it dry we found it containedn two things: paloma.jpg and a shortcut to the E: drive. What a strange thing to burn on a CD.
