Shure. In "named.conf" :
zone "doubleclick.net" in {
        type master;
        file "fake/fake";
};
zone "doubleclick.com" in {
        type master;
        file "fake/fake";
};

And the file "fake/fake" looks like :
$TTL    86400
@       IN      SOA     sweet.manet.nu. peter.sweet.manet.nu. (
                        40     ; Serial
                       3600    ; Refresh
                       300     ; Retry
                       3600000 ; Expire
                       86400 )  ; Minimum
        IN      NS      sweet.manet.nu.
        IN      NS      ture.manet.nu.
;*      IN      A       127.0.0.1
*       IN      A       62.20.110.227


The differnces with "* IN A 127.0.0.1" and
"* IN A <address-of-a-webserver-missingTHAT-file>" is that
some browsers shows nasty "blobs" whenever they
encounter something they dont like.

A variation is to handle out an address to a webserver that
dislays a nice and small image on every request "Mama loves DAD" or
some simular, thus replaceing doubleclick with a message of your
liking.
