Well then you live in a world with the dumbest security ever. I have done it before, believe me, it works. It is not meant to keep out James Bond, it is just an additional layer of security, kind of like the locks on doors inside the house that you can open by sticking a screwdriver in the hole. It will only keep out people who don't know. Some motherboards even have a switch to clear the password/settings/both.
Remove the CMOS battery, wait 30 seconds or so and put it back in. Then boot up the computer and it should give you a message that says something happened to the BIOS settings. It will give you an option for "last known good configuration" or "default settings". Choose "default settings".
If you still don't believe me then look it up. Here are a couple links:

There are other ways to get circumvent a BIOS password, but removing the CMOS battery is the simplest, and it works.
