Mylander,
"Bummer to dive and remember someone forgot to dog a hatch somewhere."
Remember the "Squalus" ? It wasn't a hatch that someone forgot to dog, the main induction hatch failed apparently. The results were a bummer though.
You want both sad and ironic, take a look at Wikipedia:
http://en.wikipedia.org/wiki/USS_Squalus
for the relationship between the "Squalus" and her sister ship, "USS Sculpin".
Fair winds and a following sea,
Old Dog
