Can Somebody Help Me Remove My Foot From My Mouth?

At my shabbos meal, I was talking to my host about different professions and mentioned one of the fields a friend of mine went into. As we were discussing it, I remarked,
"So there is actually something that can be done with a psychology degree."
"You mean besides being a psychologist," my host replied.
"Of course," I said.

Later on...
"So what do you do for a living?" I asked.
"I'm a psychologist," he answered.

I think I would have been a little embarrassed if I had connected the two parts of the conversation. However, since there was significant space between them in the conversation, I didn't realize until afterwards.

All I know now is that my mouth tastes like dirty sock.
