Why don't you just delete those kernels in Synaptic?  It will take care
of removing the extra GRUB entries for you.

"Kernels removed by Synaptic will automatically update grub.cfg and no
user action is required."

1) use "uname -a" to find out which kernel you are currently running
(e.g. "Linux shoggoth 2.6.32-19-generic...")

2) open Synaptic (System / Administration / Synaptic Package Manager)

3) ctrl-F to search for "-18", "-17"... (older kernels)

4) for each set of search results, delete the entries starting with
"linux-" and including the version to be deleted (e.g.

5) reboot and the extra menu entries will be gone from GRUB
