A while back, while waiting for a scheduled office meeting room to clear out, a friend of mine says, "They've gone over their scheduled time. It's 10:05 already."

Another manager that was waiting in the hall for the meeting then said, "No they haven't. It's exactly 10 am."

My friend says, "That's a really nice watch you have there. Is it one of those new Casios?"

Other manager says, "Yes it is. My wife bought it for me."

My friend says, "Tell her to take it back because my Rolex says that it's five minutes slow."
