Recipe seems to loop

I'm trying to use procmail to run a shell script on command.  I use a web
interface to build the shell script as the message body and send the
message out.  Then procmail grabs the message, puts the body in a blank
file that's already chmod'd to execute, and executes the script.  But for
some reason, procmail is putting 5 copies of the body into the blank file.
Here's the recipe in question:

# the poplock removal stuff
:0:
* ^TO_(_dot_)*root(_at_)wcc\(_dot_)net
* From:(_dot_)*ums(_at_)wcc\(_dot_)net
* Subject:.*superduperscripttoremovepoplocks
{
        :0bc
        /root/scripts/diepopper

        :0
        | /root/scripts/diepopper
}
/dev/null

The web interface portion is building the message correctly, as I can
comment out this recipe and receive the message with only one copy of the
shell script in the body.  I'm sure I've missed something obvious, but I
certainly can't see it.  I've tried the second portion without the "c",
but it had no effect.
