"I don't know many office managers who would take a punch for somebody"
"I don't think he meant to"
"He clocked him"
"He punched him out?"
"Whats a clock"
"Maybe lets do a demonstration"
Apparently "clock" is not the same as "punch." Urban Dictionary says "to hit someone."
Unfortunately the demonstration came to nothing. For the record, I was not a participant in this conversation. Of course I have never used clocked in a sentence though. Yet.
