[iBook] Oops, which AC cord is mine?

[Brian Olesky]

I just noticed that my wife's AC extension power cord for her 600 iBook and
mine, for my 1.5 Gig AlBook are sitting on the table right next to each
other and we don't know which is which.

The main difference is one has a 3 prong plug that goes into the wall outlet
and the other only has a 2 prong plug. Can anyone tell me which is which?

Thanks,
Brian
