If it won't boot without the password I think that it means your Dad has set a firmware passord.

Does the password box look like this

If so that is the firmware password and there is only one way of getting around it I know of, see here, specifically

Force Removing Password Protection

1) Add or remove DIMMs to change the total amount of RAM in the computer.

2) Then, the PRAM must be reset 3 times. (Command + Option + P + R).

This is by no means guarneeteed to work and I havn't perosnally tested it (read BIG WARNING)

EDIT: If it doesn't look like that see below in lamina post.

Insert the restore disk that came with the computer, hold down C until it boots to the disk, then go to the Utilities menu (in the installer) and select Reset password (I beileve).

I know there is a way to do it within the installer. You can probably do it from the Leopard installer as well.

Sorry for the non-difinitive answers.

Edit: Didn't consider what xUKHCx wrote. However, if it's a firmware password, he'd likely remember it isnce he wouldn eed ot enter it every time the computer boots, no?

Well then see what lamina wrote.

The firmware password only kicks in when you try to do something funky such as boot key sequences or install an OS.
