You can also just use
sudo su
and keep the root account without password.

2Once I understood I can do this, I did "passwd -d root". Thanks! – ripper234 Mar 17 '11 at 13:21

If you have your sudo password then try the following (this is on Ubuntu 14.04LTS):
ewan@user-sbc-ihsw:~$ sudo -i
[sudo] password for ewan:
root@user-sbc-ihsw:~# passwd
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
root@user-sbc-ihsw:~# whoami
root

you can also use sudo with the "-i" option. this will log you in as root without using the su command.
sudo -i

You can change all these options in sudoers file, even make no password if you want( I would not recommend this though).
