Clear all signatures on key?

[Tech]

Hello,

I'm trying to figure out how to remove all signatures from all my GPG
keys. I've RTFM but I've missed something I'm afraid. Here is what I am
seeing:

1. Type "gpg --list-keys" and I get a list of my keys. (me at me.com is a
fake email address for the sake of this post...)

2. I type gpg --edit-key me at me.com

I am now in edit mode

Command> list

(I get my key information)

Command> uid 1

(I then select my key)

Command> Delsig
Nothing deleted.

Command> Minimize
User ID "My Key etc etc":
already clean.

Command> check
uid "My Key etc etc"
1 user ID without valid self-signature detected

Command> quit



3. I type 'gpg --list-sigs" and I get a list of keys thusly:

C:\Documents and Settings\Administrator>gpg --list-sigs
h:/gnupg-keys\pubring.gpg
-------------------------
pub   1024D/XXXXXXXX 2005-08-10
uid                  My Key (Email Encryption/Signing Key) <me at me.com>
sub   4096g/XXXXXXXX 2005-08-10 [expires: 2006-08-10]
sig          XXXXXXXX 2005-08-10  My Key (Email Encryption/Signing Key)
<me at me.com>



Question: What signature is listed there that is reported from my
--list-sigs command? What have I missed? I would think I have no
signatures installed on my key?

Thanks for the help and info,
