How do I (and do I even want to) delete outdated versions of the Linux kernel?

I notice that GRUB (or is it GRUB2?) asks which version of Linux I'd like to boot, and outdated versions of the kernel are listed. How do I remove these and their associated files to save disk space? Since I'm new to Linux, is there any reason why I shouldn't remove them?
