<human>: Can you condense the text into a few key points?

This happened about an hour ago.

I'm a poker dealer at a casino. I just got off the night shift (10pm-6am) and need to share!
 It was nearing the end of my long monotonous shift and my last hour was spent dealing Hold'em bonus to one old fella. After quite a few hands, he asked what time it was. 
Now there is a giant clock kind of tucked away by some kiosks off the gaming floor. It's far enough away from players that they don't know it's there or can't see it to read the time. They also can't see it because it's black so very hard to read the time unless you're right in front of it. Apparently I have incredible vision because I can see the time just fine from a good 25 metres away. I check the clock and reply. 
Me: "It's 5:20 sir" 
Player: "You're not wearing a watch, how did you know that?"

As my mind started working faster than my speech, I realized I was about to say big black clock. I knew it would be easy to mess it up, being tired and of perverted mind most of the time. I was sure I would say big black cock. So I took my time to ensure I said the opposite of what my messy tired mind would want me to say. 

Me: Behind you...that big black cock

Nope! Still fucked up.

As soon as I said it, the player turned around to look (maybe he heard clock and not cock) and we were greeted by a 6'3" 250lb black man. My player may have heard clock...but this man DEFINITELY heard "big black cock". 
He gave me the stink eye. I kind of panicked and didn't know what to do other than point again and say in cave man style "Look! Big black CLAAAWwwwkkkk". He looked at me again and then continued with his roulette game. 
Dodged a bullet, but still took a pellet.
<bot>: tried to point customer in direction of big black clock. Accidentally said big black cock. Black man thought I was talking about him.
