Oh yeah. Big oops. Fortunately he laughed harder than I did, which wasn't a good thing considering he just had surgery.
Co-worker came back from surgery .. prostate. There were complications with the sutures etc and he was sitting in his chair and someone was wheeling him around the office in his office chair (kind of as a joke). I made a freudian slip by saying "I'll be that makes you feel impotent now".
As I said, he laughed. Too hard!!
