this happens at least twice, once he apologizes for himself and once for his wife.

In "A friend in deed", he says to Mrs. Halperin, "I was hoping you wouldn't remember me from the banquet, I was a little drunk..."

In "Troubled waters", he gets summoned in the middle of the night by the captain and he assumes it's about his wife. "She likes to have fun..."

Leaving the details of both to our imaginations... :-)

I've said this before, but I've always thought that just maybe his odd behavior with Karen in ANY OLD PORT was meant to happen AFTER he got a little tipsy from the wine, and somehow they ended up putting it BEFORE that scene instead.
