The other day DOB and I were making a list of top phrases you don't want to hear during surgery. Like this:

OK, now, which side was it on?
Sterile, schmerile--we mopped yesterday.
Hey, what's this doohickey for?
Did anybody see where that sponge went?
Was that in milligrams or micrograms?
I must have slept through that lecture.
Oooops.

But in the hospital silence may be even worse.
