Sounds like...

Murray slipped up.  He's usually pretty good about watching his language around the kids, but in a moment of frustration he yelled "God Almighty!"  Christian took notes and filed it away for later.
At dinner, he couldn't fork his salad and yelled "God Almighty!"  Murray and I looked at each other and went into recovery mode...
M: "Gotta Buddy?!"
C:  "NO!  God Almighty!"
J: "Got all muddy?!"
C: "No Mommy...God Almighty!"

We are looking for suggestions to help throw him off.
Sooo glad it wasn't me...this time.
