No, but it is interesting to know methods like this.

You can achieve admin on an OS X machine by adding a new one like so:

1. Enter single user mode via cmd + s during startup.

2. Mount the hard drive via /sbin/mount/ -uw /

3. Delete the setupdone check via rm /var/db/.applesetupdone

4. Reboot, and now you are presented with the wizard for adding a new admin account.
